When Brian Rodgers came to visit in June, he brought his drone with a new lens that promised great opportunities. The drone offers remarkable views that can really capture the beauty of the landscape here at REGUA, it is also a very necessary tool to help us understand the importance of the conservation work going on.
Supported by Saving Nature, Brian arrived with two students Ian Handler and Ryan Huang from Duke University, in North Carolina, USA. Their plan was to help set up camera traps, in strategic places around the reserve, and also to continue their scientific research at the Golden Lion Tamarin project in Silva Jardim.
Brian helped REGUA secure the Vecchi land corridor last year, an important strategic purchase to link the Vecchi ridgeline with Onofre Cunha, land which REGUA already owns and protects. Brian was delighted to see the progress we are making in planting this pasture land to create a forested link.
This diurnal snake, was seen by a group of visitors on our Green Trail, whilst walking in the forest with Adilei.
Although not venomous, they can still give a nasty bite if threatened. Adelie knows how to deal with this sort of situation as he has spent all his life in these forests. One of the group got this amazing footage, standing at a safe distance.
These snakes lay eggs and are active on the ground and in trees. Their prey are mammals and birds, including eggs and nestlings.
Their defence strategy is to puff up their forebody and shake their tail. This individual seemed quite relaxed and only shook the tail as it left the group by slithering under a nearby fallen tree.
Michael Patrikeev, a long standing friend and supporter of REGUA is always coming up with amazing information on his sightings while at the Reserve. The latest concerns two species of large grasshopper found at REGUA. Here’s Michael’s report and excellent photographs.
“I have identified two species of Tropidacris from REGUA
Tropidacris cristata (Giant Red-winged Grasshopper) is the largest known grasshopper, reaching up to 14 cm in length, and 24 cm wingspan. The adults are olive or brownish-green, with orange hindwings. The nymphs are striped with black and yellow, and likely toxic. This species inhabits forested areas of Central and South America from southern Mexico to northern Argentina, and the island of Trinidad. In flight it resembles a small bird.
Tropidacris collaris (Giant Violet-winged Grasshopper) is found in tropical forests and grasslands of South America east of the Andes, from Colombia to Argentina. Along with T. cristata, this is one of the largest known grasshoppers (length around 10 cm, wingspan 18 cm). The adult is mostly green, yellow-green or brown, with blue hindwings. This species is more common than T. cristata.
I have photographed only nymphs of these species in REGUA, but would expect one of these to come to a light at the Reserve sooner or later – they are quite a sight!”
Both species are widely distributed in the Neotropics, and common. T. collaris occurs in both forests and savanna, and T. cristata is mostly a forest species.”

It’s amazing how things can change in a year. It’s just over a year since I was last at REGUA, and so much has happened.
Most noticeable to the lodge visitor is the tapir release project where five Lowland or Brazilian Tapir (TapirusTerrestris) have been released at the nearby wetlands, they often make the short trip up to the lodge garden. It is surreal to see guests at night photographing moths at the moth wall, with a rather large mammal wandering past on its evening patrol, both seemingly unaware of the other.
The Tapir have managed to get food off the garden feeding stations so a suspended higher-level table has now been made. The Common Marmoset (Callithrixjacchus) were a little perplexed initially but soon mastered the art of a trapeze-style dash across the wires. Some continue the more traditional approach – head first down a nearby tree.
The lodge orchid garden continues to develop, and with ferns and bromeliads amongst the rocks it makes a breeding area for house wren and feeding area for hummingbirds, the lantana and milkweed are doing well, again both favourites with the hummingbirds.
Other changes may not directly affect our lodge guests but they are making a huge difference to local visitors, including school visits, with a new car park by the conservation centre – hopefully no more buses getting stuck in the mud! A new accessible trail has been created to Amanda’s hide, bringing opportunities where previously it would have been impossible for some people to enjoy the delights of the wetlands.
On the project itself, we reached the milestone figure of 500,000 trees planted and continue to plant – over 69,000 trees were planted in the 2017/18 planting season alone, thanks to the generous donations from many of our supporters.
Wouldn’t one million trees planted be a great figure to reach in the future!
With more key land areas coming under REGUA’s care, increased wildlife corridors are being protected and created in the Guapiaçu catchment area. This will extend the range for many species of wildlife and enable them to strengthen in population, increase genetic diversity and increase the overall biodiversity of the valley.
Our Rangers continue to patrol the forest, adding security and monitoring the wildlife, whilst there has been a huge reduction in hunting in the area since the project began, we cannot stop our vigilance even though there is very little evidence of hunting seen or heard now.

Climate change is predicted to increase the intensity of extreme climatic events such as severe droughts. Littleis known on how freshwater ecosystems respond to severe droughts in the neotropics. Terrestrial organic matter, primarily derived from plant litter, represents an important food resource in these nutrient limited freshwater ecosystems.
ThePhDprojectcurrently being undertaken by Camille Bonhommefrom Universidade Federal do Rio de Janeiro(UFRJ) wants to investigate the effects of quantity of terrestrial mattersubsidies on the response of the recipient aquatic communitiesto drought stress.
Camille will use tank bromeliadsalong with their associated aquatic invertebrates as model ecosystems. Tank bromeliads are neotropical plants. Their interlocking leaves form rosettes that collect rainwater and dead leaves from the overhanging trees, creating an aquatic habitat for various species of invertebrates.
In the field experiment, bromeliads will receive either few or high quantities of leaf litter inputs. After a natural colonisation and equilibration period, the diversity and composition of the aquatic invertebratecommunity that colonised the bromeliadswill be assessed and compared to the quantity of subsidised resources. Thebromeliad micro-ecosystems will then be submitted to a drying and rewetting event, to assess their resistance and resilience.
Camille hopes to show firstly that the variations in leaf litter provision will determine the composition and quality of the colonisation (includingnumber of species, food chain length and overall community composition).
Secondly, that the leaf litter quantity will affect the stability of the community submitted to drought, expecting the higher provision of leaf litter to give greater support, by offering a “buffering” effectto the community. It is hoped to show that leaf litter will provide short term refuges for invertebrates and be more attractive for recolonisation after the drought.
We look forward to seeing the result of Camille’s research.
Last weekend REGUA received Thomas Brooks, Head of Research at Geneva for IUCN.
In between seeing birds in the day and waiting for the owls to call in the evening, we discussed the importance of monitoring, something talked about at the recent World Land Trust conference in Thetford UK.
He also asked us about long term sustainability. I told Tom that we believe REGUA will continue to grow and reach to tourism, education and research income streams and that we look at the protection core costs such as Ranger work being covered by Eco-service payments.
As there is increasing evidence that forests produce water, we believe that grants will be available in the near future that provide annual fee given to those proprietors who have forest cover.
Ants belong to the Formicidae family, one of the most important in Nature, pillars of the ecosystem. Divided into Tribes, the Attaand Acromyrmex are very common in our Neotropical forests and though we worry about their action in freshly planted forests, they are very important in the established forest harvesting and cultivating their fungus on which they feed in their underground homes.
Their vast system of perfectly ventilated tunnels and chambers permits precious nitrogen to reach the roots of trees.
We are trying to identify the most common species at REGUA but we expect to have between 400 and 450 different species. Taking photographs is notoriously difficult, for aside being small, they move and are often camera shy.
