We had Eric Fisher’s visit who played an important role in this event.
The Bioblitz aimed at registering as many organisms (animals, plants, fungi) as possible! REGUA was also part of a worldwide DISPUTE among more than 400 cities and regions in which we will be able to show the great biological diversity in aquatic Atlantic Forest and Restinga ecosystems and also in urban areas of our Municipality.
The event has 2,140 observations, 88 participants and 880 identified species so far, and more to be added.
We were unable to make this event open to the public due to Covid-19 pandemic however we think it is very important to engage in citizen science practices going outdoors appreciating nature’s fabulous diversity. We already did some great observations and we are excited with the prospect of contributing to the global citizen science platform Inaturalist!

Every evening, for the last six months, REGUA´s Visitor Centre wasvisitedby a mysterious nocturnal animal. It was common to see pellets and white stains on cars and all over the floor first thing in the morning. Wefinallyfound outthat the elusive creature was a Barn-owl (Tyto furcata)! Itisnestingatthe top of an oldtree byREGUA’s common area and feeding on small vertebrates.
Widelydistributed, thisspeciesoccurs in alltheAmericas, except for thedenselyforestedregionsoftheAmazon. Barn-owls inhabit open andsemi-openareasandthey are more activeatduskand at night. They arecommonlyseenflyingloworon top offencesalong theroad. Duringday time, they sleepornest in churchtowers, atticsofhousesandtree hollows. Anunmistakablefeatureofthespeciesistheirheart-shaped face. Males andfemales are quite similar however,the male maypresent a whiteunderpartwhilethefemalemaypresent a cream to light browncolourunderpart.
Barn-owls feed on rodents, invertebrates and some largermammalsandsmallbirds. Studieshaveshownthat this species is able to separate different materials in theirstomach, including hair, bonesandother non-digestibleparts. The pellet cycle is regular, regurgitating the remains when the digestive system has finished extracting the nutrition from the food. This is often done at a favourite roost. When an Owl is about to produce a pellet, it will take on a pained expression. Owl pellets differ from other birds of prey in that they contain a greater proportion of food residue. This is because an owl’s digestive juices are less acidic than in other birds of prey.
Scientific research, contributes to the generation of local knowledge and helps the scientific community to fill in several gaps and areas of knowledge that still need to be investigated.
This week we have the visit of two researchers, Ederson and Beatriz, from the Federal University of Rio de Janeiro (UFRJ), who are looking for Amalactus carbonarius species larvae. This beetle belongs to the Curculionidae family, known as Weevils. It was found recently that this species finds shelter on the Southern Cattail (Typha domingensis), which is found at REGUA’s wetlands.
Typha domingensis is a very invasive plant spreading freely when in a suitable site. This is fine when growing on its native habitat, but the plant can become a serious weed in managed aquatic systems worldwide.
For that reason, it is important to keep the right balance between the area these plants occupy, in order to guarantee a minimum number of individuals that can shelter different insects.
The Rufescent Tiger-Heron (Tigrisoma lineatum) is often seen at REGUA’s wetlands. This species belongs to the Ardeidae family and inhabits Central and South America. Its head, sides of the head, and long, thick neck are rich chestnut brown to rufous cinnamon. The bill is relatively long, up to 10 cm, appearing slightly up tilted, and varies in colour according to age and season, in ways that are not well understood. Immature birds are variable, undergoing gradual plumage changes through the fifth year. The adult Rufescent Tiger-Heron is identified by its rich chestnut to rufous brown neck and head, dark and white lined throat, dark flanks with narrow white bands, white banded under wings, and relatively long neck and lower legs. Male and female reaching adult age are alike, although there is an indication of sexual difference in plumage details.
This species inhabits wooded tropical swamps. It occurs especially along slow-moving rivers in swamp forests, gallery forest, mangrove swamps and in other extensive forested wetlands. It is a typical bird from the great wetlands of South America, the Amazon, the Paraguayan and Argentinean Chaco, and the Brazilian Mato Grosso. It is common to spot them on rainy and dark days, as they seem to be lonely bird. Their nests are often built on top of trees and shrubs, composed by many sticks. The breeding season is not well documented and there is a need for additional study. Its diet includes fish, amphibians, insects, and snakes. Its long tarsus, bill, and neck suggests a primary adaptation for fishing. When they feel threatened, they remain motionless until they finally fly, finding shelter on top of the trees.
These pictures were taken by Claudia Bauer, a renowned Brazilian ornithologist who belongs to a birdwatcher’s club in Rio de Janeiro. She often comes to REGUA to photograph birds and nature. It is an inspiring hobby!
On March 1st 2019, the UN General Assembly declared 2021-2030 UN Decade on Ecosystem Restoration. There exists an urgent need to accelerate global restoration of degraded ecosystems to combat climate change and biodiversity loss. Healthy ecosystems are essential for sustainable development that contributes to poverty alleviation. The UN Environment Programme and UN FAO (Food and Agriculture Organization) are leading the global movement which includes over 70 countries committed to restoring more than 170 million hectares of degraded land worlwide. Ecosystem Restoration implies environmental,social and economic gains through which people´s well-being and nature´s resilience is enhanced.
REGUA is one example of good practice conducive to these global goals.
Among the few students who visited REGUA last year, a very atypical year in which most universities’ field trips were cancelled due to Covid-19 pandemic, PhD student Beatriz Ferreira proceeded with her research topic of evaluating how pasture management with isolated tree clumps decreases the effect of deforestation and encourages the presence of Anuran tadpoles in pasture puddles.
Anurans use these ponds for reproduction which become fundamental to their existence. Jefferson Ribeiro and Orlando de Marques Vogelbacher accompanied Beatriz on her last 2020 field trip to REGUA. They are both Biology PhD students and have taken beautiful pictures of flora and fauna found at REGUA.
For the last 20 years, REGUA has been encouraging and supporting research carried out by national and foreign universities.
Research at REGUA is one of the main pillars on which we base our conservation mission in the upper Guapiaçu watershed. Ultimately, understanding the dynamics of nature allows us to acknowledge that Mother Earth’s environmental services are paramount to human permanence on the planet.
We hope continuing welcoming researchers and students this year.
Plants belonging to Dahlstedtia genus occur exclusively within the Atlantic Forest in Rio de Janeiro, Paraná, Santa Catarina and Rio Grande do Sul states in Brazil.
This genus is represented by two species: D.pinnata and D.pentaphylla. However, some specialists consider the genus as monotypic. Dahlstedtia plants grow both as bushes and trees. Hummingbirds regularly visit their beautiful pink or reddish flowers.
Locally known as “Timbo”, its roots and bark were used by indigenous people to dumb and asphixiate fish as part of their fishing practices.
This Dahlstedtia was found and photographed within a new acquired area by REGUA.
The “Bosques da Memória” Campaign 2020 is all about planting trees as a tribute to COVID-19 victims, and a way to thank doctors and those working in hospitals in Brazil.
We are all going through a difficult year due to the Covid pandemic, forcing us to slow down and adapt to a different life style. This only adds to the climate crisis and the forest fires and deforestation, which have destroyed many forests in Brazil.
This campaign offers us some hope to change the loss of forests, reminding us of the risks of climate change.
Trees to be planted at REGUA will be dedicated to those impacted by Covid. There are already 21 sites sharing in this campaign across the country. The idea is to involve different conservation institutions, NGOs and those individuals who want to take part.
Anyone who feels like dedicating the memory of a lost one through planting a tree, please contact us.
The Dutchman Jean-Paul Boerekamps visited REGUA in 2018 and returned last week in spite of the global Covid scare, to complete a Bioblitz around the mountainous region of Nova Friburgo and also at REGUA. Though a birder, he has become increasingly a Naturalist and through the digital platform “Inaturalist”, he came to SE Brazil with the mission of photographing and uploading images of all creatures and plants, and inspiring others with his passion!
REGUA’s Bioblitz lasted a week and together we managed to make one thousand different species observations, half of which have been positively identified by the Inaturalist community. JP visited “Waldenoor”, a restored area that slowly shifts into a more mature forest; the green trail, where he was accompanied by Rildo de Oliveira, in charge of patrolling/monitoring the highest and most preserved forests at REGUA; the “Fragment”, where he could walk through a special remnant of well-preserved lowland forest; and the Vecchi reserve, 15 km away from REGUA, composed mostly by open areas, allowing whoever visits it to have a good idea of local biodiversity.
JP photographed many moths that came to the moth wall every evening, attracted by light that strongly stimulates/excites them. One special observation was a moth belonging to the Notodontidae – subfamily Dioptinae.
According to our butterfly expert Jorge Bizarro, this is an uncommon species, which is difficult to identify. Jorge knows that it belongs to the subfamily Dioptinae, a group of diurnal Neotropical moths, many of which have bright winged colours. Identifying certain species on i-naturalist is never easy, so sharing one’s observations allows one to practice the concept of citizen science and allows one to exchange knowledge with others similarly interested in th same subject. This process allows experts and beginners to exchange information.
Now that the Bioblitz is over, we can add observations to ‘REGUA Biodiversity Celebration’, a long term project that is soon to reach 10 thousand observations by the end of this year. If any of you would like to help us, any of you who have visited REGUA may contribute to this project by uploading previous observations. It’s quite straightforward; you just need to create an Inaturalist account and upload your photographs from your computer or your phone. We would really like you to help us achieve this result. Here is the link; https://www.inaturalist.org/projects/regua-biodiversity-celebration and add your sighting! Thanks JP for sharing your passion with us all here at REGUA!

REFAUNA Tapir reintroductionprogrammeat REGUA started in 2017 andis supported and implemented by Rio de Janeiro Federal University (UFRJ), Rio de Janeiro State University (UERJ), Rio de Janeiro Federal Rural University (UFRRJ) and Rio de Janeiro Federal Institute (IFRJ). To date, 11 tapirs (femalesand males) havebeenreintroducedwithinREGUA´sland.
In August 2020 we had the female tapir Jasmin arriving at REGUA. She came from Guarulhos zoo, in São Paulo, and spent about 3 months on the release pen to get familiarized with the new environment. There were feeding points set up by one of our staff members, Sidnei, who came every day to feed Jasmin. Finally, the release day arrived! It was meant to happen the previous day; however, Jasmin was a bit moody and nervous, so she threw herself into the puddle and didn’t leave the release pen area. Only today we managed to open the gate allowing Jasmin to leave the release pen without hesitation. These next days are very important to keep track of Jasmin. She is being monitored by a tracking collar and she will probably be looking for a place to settle.
The Water Quality Monitoring Programme is an integral part of Guapiaçu III Environmental Education scheme at Regua. This initiative aims at raising young people’s awareness of water resources, its use and its care indicating the association between forest and water provision.
The programme targets Cachoeiras de Macacu and Itaborai municipal and state-run school students who are trained to collect and analyse the Guapiaçu, Macacu and Caceribu river waters. Water sampling (physical, chemical and biological elements in the water) takes place at 12 different sites both upstream and downstream urban areas of the referred rivers.
Covid-19 pandemic outbreak at the beginning of the year forced this programme to be held online with no water sampling trips organized. In October, the project team reinstated the latter following strict guidelines from health agencies including the use of personal protective equipment and working with small groups. The reinstated water sampling trip was carried out at point 7, in Boca do Mato neighbourhood which is located upstream Cachoeiras de Macacu town. Students were able to learn about benthic macroinvertebrates, which are water quality bioindicators.
Water sampling awakens a new approach to water use in young people in addition to being a very different and fun activity. 45 Environmental Monitors in Cachoeiras de Macacu were trained and are now ready to assist Guapiacu III project team in this programme. Guapiacu III project is currently starting the on-line Itaborai municipality school students´s recruiting process.
After the tree planting period, the phase known as post-implementation consists of the maintenance of the future forest. It is important to protect planted saplings especially from the negative effects of opportunistic weeds, insects such as the leaf-cutting ants and diseases. When necessary, new seedlings are to be planted replacing seedlings which have not flourished. These measures are taken to offer ideal conditions for the development of the seedlings, as well as to promote their establishment. A successful reforestation programme depends on efficient management and its periodicity. In general, maintenance should take place every 90 or 120 days, counted from the planting day or period. On a long-term period, maintenance contributes for the reestablishment of ecological services.
Ecosystem services provided by a restored area can improve local and regional microclimate, water regulation, stability of slopes, increased quality and quantity of water resources and the reestablishment of biodiversity through the connection of forest fragments.
To verify whether the new forest is developing well and fulfilling its ecological role, it is necessary to monitor and evaluate its growth. We have two monitoring steps: the first one, which follows INEA (Environmental State Agency in Rio de Janeiro) Resolution No. 143 from 2017, that checks the quality of restored areas; and the second one, which evaluates the accumulated biomass and carbon stock in restored areas by ‘Guapiaçu Project’ Petrobras funded project.
The first stage of monitoring happens annually after the tree planting has taken place. The main purpose is to fulfil commitments and legal obligations following INEA`s resolution. At this stage, the methodology chosen is the Rapid Ecological Diagnosis – DER. The procedure to monitor the restored area’s development is based on the direct measurement of seven ecological parameters, which are: density of the planted area, percentage of zoochoric species, height of plants, equitability of individuals, species richness, canopy and grass cover. While measuring these parameters, the spontaneous arrival of new individuals of plants on the restored area can be verified, some older trees are expected to be flowering or fruiting (especially the pioneer species) and also animals on site should be able to be noticed, such as insects, birds, rodents and small mammals.
The second monitoring stage is carried out when four years have passed by. The first 100 ha tree planting that took place in the first stage of the Guapiaçu Project between the years of 2013 and 2015 received carbon certification by the Biodiversity Community Climate Alliance (ACCB). This certification provided a quality seal to these reforested areas. Tree planting carried out in the subsequent phases of this project (more 160 hectares) were incorporated into the biomass accumulation monitoring plan, according to the methodology and assumptions certified with the ACCB, and will be able to receive certification after completing four years since implementation.
Biomass monitoring takes place from the fourth year on because it requires the saplings to have their DBH (Diameter at breast height) more developed so that one can use it as a parameter in the application of allometric equations. These equations are used for the analysis of biomass and carbon stock in the plantations, as well as to obtain the values of CO2 sequestered by the new forest. With that, REGUA took the commitment to monitor the biomass accumulation in these plots over the next 30 years. Over this 30 year span, more than 13,500 tons of carbon are expected to be stored and 49,680 tonnes of CO2 equivalent to be removed from the atmosphere.
We have had a very sad news recently, the tapir Eva was hit on a dirt road by a motorcyclist, and days later was found dead. Luckily the motorcyclist was not seriously injured. Eva’s eight-month-year-old male offspring has not been hit. We’re setting up reinforced feeding points where Eva often used to visit with her baby, so we’re going to monitor him very closely.
Accidents involving wild animals are a major problem worldwide, it is estimated that 475 million wild animals are run over each year on Brazilian roads. In the case of large animals such as tapirs, these accidents can cause serious trouble. Respecting speed limits and driving carefully on roads near natural areas are ways to avoid these types of accident. Refauna together with Guapiacu III Petrobras funded project and REGUA are providing, with the support of the municipality of Cachoeiras de Macacu, speed reducers and signs for the road near REGUA, to reduce the chance of more accidents.
Eva was the first female tapir to be reintroduced at REGUA. She lived in the wild for almost three years and left two cubs. When she arrived at REGUA, she was very shy and didn’t come too close to people, but after being released, in few months, she didn’t approach anyone any longer, behaving like a wild tapir. She established her territory between REGUA and other rural properties and could be spotted walking with the other reintroduced tapir Valente, the baby tapir’s father. She fully adapted to the wild, as if she had never lived in captivity. We have learnt a lot from the tapir Eva and we are very saddened with her death. It comforts us to know that she had the chance to live a happy life in the wild and that Eva’s reintroduction helped us to gain experience for the reintroduction of other tapirs into the wild. Let’s hope her baby tapir lives a long life in REGUA’s territory.
Have you ever comeacross with thischarminglittle bromeliad?Tillandsiastrictaiswidely spread throughout South America and inBrazilitoccursfromthestateofBahiatoRio GrandedoSul.It is usually an epiphytic organism that can be found inforests, rupestrian grasslands andinthecaatinga region.

This is the Eueides isabella dianassa, belonging to the Nymphalidae family, subfamily Heliconiinae. This species flies all year round, however is often seen on the drier months of winter.
This species has a short life cycle, about 2-3 months and often remains close to the host plant (passion fruit/passifloras) where larvae feed on their leaves. The female is slightly larger than the male and lays isolated eggs on the underside of the leaves. The larvae, known as caterpillars, feed on leaves by scraping the lower surface while they are small.
Eventually when they become larger, they gnaw the edges of the leaves. When they reach the fifth age (after changing ‘skin’ 4 times to continue growing after stretching) instead of changing the skin, they abandon the plant and look for other sheltered places (walls, windows, dry wood or tree trunks) where the pupa or chrysalis is formed, staying another 4 to 6 weeks until the adult butterfly emerges.
On a sunny winter afternoon, mating was recorded. The males performed an “8” shaped movement around the female releasing pheromones. The female, already receptive, had her motionless abdomen waiting for the male. There were 3 males flying around the female, but in this case, the female only chose one to mate.
In spite of the the Covid-19 pandemic, forest restoration is proceeding at REGUA observing all the necessary measures to safeguard the staff´s health. Already 18 hectares have been planted within the “Armenio” land in the vicinity of Matumbo village.
Thirty thousand seedlings of 113 Atlantic Forest different tree species were planted since February this year. Aside this, the maintenance of the 60 hectares planted in 2017-2019 has also been completed and we are now in the process of planting five hectares belonging to REGUA´s partners as part of the Petrobras socio-environmental Guapiaçu III project. Brazilian Forest Code obliges land owners to restore hillsides with slopes over 45º, hill tops, water springs and riparian vegetation alongside rivers and streams. REGUA is making this available for partners who share the same conservation vision within the Guapiaçu watershed.
The Environment Week (01/06 to 05/06 2020) began with the viewing of the “Grande Vida” trail from home. The narrated tour begins on the Yellow trail and reaches the wooden bridge in which the viewer is accompanied by the sounds of nature, specially of birds that often can be seen and heard at REGUA’s wetlands. It is possible to select icons such as photos and self-explanatory posters that are present along the trail showing the Atlantic Forest biodiversity, animal tracks, view of the wetlands, forest dynamics and some of the conservation work carried out at REGUA.
The idea is quite innovative, even though there are already some virtual visits in National Parks across the country. What makes it different is the fact that it was made in a Private Nature Reserve (RPPN). It is worth mentioning that home office has changed the routine of many professionals worldwide, however this is far from preventing people’s contact with nature. Thus, it is essential to share contents with technological tools, as well as to keep up with digital media trends. The Environment Week was also featured with several live sessions broadcasted on Instagram, covering topics related to other projects financed by Petrobras that are part of Guanabara Bay network. All of these initiatives are a means to bring a little inspiration to those in quarantine respecting social isolation.
The Yellow Rat Snake Spilotes pullatus, a semi-arboreal species, which feeds on small rodents, amphibians, lizards and even other snakes, is easily found in forests, in open areas such as pastures and trails and can even be seen around human constructions in search of food. Despite being a large snake, reaching up to 3 metres, it’s very agile and not venomous, with yellow and black colors.
Recently, an old skin left after shedding (the process being called ecdysis) was found at the research accomodation, Casa Pesquisa, which in adult individuals occurs on average once a year. This process occurs when the outer layer of the skin, formed by keratin, is replaced by a new one. This exchange takes place when snakes, in general, grow or when the outermost layer is damaged. Ecdysis lasts from 5 to 7 days and during this period the snake becomes more vulnerable to predators as vision is reduced due to fluid accumulation between new and old skin.
