These great 4 year olds and staff from Headstart, Quebrada Arriba, Patillas, spent a really fun morning at Las Casas de la Selva, looking closely at all kind of plants and animals in the forest, with Andres and 3t.
George LoCascio from Bunkerhill Community College in Boston, returned to spend a few days at Las Casas de la Selva, along with Denise O’Malley, helping out on gardens and continuing with George’s ongoing Lepidoptera project. This consists of a species survey and a population survey. The species survey involves the use of aerial mesh traps, that carry fruits as bait to attract butterflies,that remain unharmed for proper identification. Along with aerial traps traditional hand nets are used to capture species for identification. Both methods are used to compile a list of Lepidoptera species that are found on the property. The population survey is along a predetermined 1.1 km transect that can be, and is, repeated to find population trends of different known species. George and Denise also continued with a project begun last year, measuring the volumes of tree trunks and using the density of the wood to determine the amount of carbon dioxide that has been sequestered within them. George has been returning to Las Casas frequently over the last few years. This was Denise’s second trip here.

A team of Fountain Valley High School students from Colorado Springs, CO, spent five days with us. Led by Andrés and 3t, the students completely emptied out the entire woodworking and machine shop, cleaned and organized all the tools, cleaned machines, took out all the wood stockand re-organized it, and left the workshop clean, organized and far more user-friendly! Students also worked in the nurseries and trails with Norman. Thank you to Deb Prantl and Vydia Garcia for tremendous team leadership, and a super big thanks to all the students who carried out such an incredible task. We really appreciated your help, and also the constant smiles and endless enthusiasm.
Please come back in the future!
Genny and Tim, spent 10 days with us during the Appalachian State University group’s visit, and helped with all aspects of the project. We really appreciated their wonderful company, super hard work, and enthusiasm! They are off to spend more time at our sister project Synergia Ranch, Center for Innovation and Retreats, in Santa Fe, New Mexico. https://synergiaranch.com/about-us/
Appalachian State University students worked really hard on a diversity of projects at Las Casas de la Selva; plastering the bunkhouse, making a ramp for access to the dining room, pruning, gardening, nursery work, moving soil, making a new compost, emptying the humanure compost ready for use, and many other tasks. Wow! We thank you all for being such wonderful company this last week. We’ll see you again!
Vanderbilt University students have just spent several days with us at Las Casas de la Selva, and we have had a super time, working hard! Students learnt the art of plastering on the bunkhouse, led by Andres, and also helped with heavy labor and soil renewal on the Papaya Terraces with 3t. In their time here, they also got to do a leaf litter study with Norman and hiked into the forest. Thank you for your remarkable teamwork, and thanks Zach and Julia, team leaders who did a great job. We salute you all! Come back and see us again soon.
Vella Lovell, a student at The Julliard School of Dance, Drama and Music, NY, volunteered at Las Casas de la Selva for the days that Vanderbilt University students were here. Thanks for all your hard work and enthusiasm lovely lady!

This was our third year hosting a team from Pepperdine University at Las Casas de la Selva. Norman Greenhawk, as crew leader worked with the students on the main hill-trail and everyone worked super hard to build steps, and to make the walk up and down the hill much safer and more comfortable. Hauling rocks and gravel from the river and carrying then up hill was hard work, and it was extremely satisfying to us to see a group getting on so well with the task at hand. The materials used were recycled from all over the homestead and the wood was from the old drying shed that Pepperdine students helped us to deconstruct in 2013. The work was muddy, and in rainy conditions for a few days, but sunshine prevailed and we all had a superb time with this great bunch! Pepperdiners, we salute you all. Please stay in touch.

3t, Andrés, Norman and Magha appreciate the work and great company of Fryeburg students, February 2014
This wonderful team from Fryeburg Academy, worked with Andres and 3t to build the new nursery for the endangered endemic tree planting program. We have had a super time and we thank you all for help in clearing, pruning, tidying, and generally being a great clean-up crew on the homestead too! And in rainy conditions! The team also spent time with Norman on trail work, and carried out a frog study on a night-hike.
Thanks to Chris and Emily for bringing such a great team our way this year. We look forward to seeing Daniel at age three next year!
This program has been formulated to protect endangered flora and fauna by planting endangered endemic tree species, and working on habitat enhancement in subtropical wet forest. The location and the quality of the habitat of the 930-acre forest property of Las Casas de la Selva is ideal for the establishment of projects toward the recovery of various endangered endemic tree species. The property’s north-eastern border adjoins the Carite State Forest which contains another 6,660 acres of subtropical wet mountain forest land.
Tropic Ventures Research & Education Foundation are collaborating with US Fish and Wildlife Service (FWS) to develop habitat enhancement and restoration projects that benefit endangered endemic species of Puerto Rico

With Fryeburg Academy…
Fryeburg Academy students from Maine, are here helping us for the next several days. Led by Chris and Emily Strahler, they are working on composts, trails, but mainly on the new tree nursery for our endangered endemic tree planting program.

And two year old Daniel going with the flow….
Norman Greenhawk was away from Las Casas de la Selva for the majority of 2013, from April through Mid-November, on travel and training on the Earthwatch Neville Shulman Award for Emerging Environmental Leaders. Norman won the award based on his proposal to study not only various species of reptiles and amphibians, but also to conduct ethno-herpetological interviews with local people through Central and South America to record attitudes, uses (medicinal, ritual, economic, etc), and beliefs about frogs, snakes, lizards, and crocodiles.
Norman’s travels took him to Panama, where he studied with the brilliant Dr. Julie Ray of La MICA and with the Smithsonian’s Panama Amphibian Rescue and Conservation project. Norman learned to catch and relocate endangered crocodiles with the American Crocodile Education Sanctuary in Belize. In Honduras, Norman learned the finer points of monitoring the endemic Utila Island Iguana, a species of lizard that is adapted to inhabit only the mangrove swamps of Utila Island. Norman ended his trip with a month in Bolivia, studying critically endangered frogs and interviewing the indigenous people who ran the “Mercado de las Brujas”.
Upon his return to Las Casas, Norman led an expedition into Icaco Valley with Jan Zegarra of the US FWS, and Maria Cristina of Universidad Metropolitana. The purpose of the trip was to monitor the population of Eleutherodactylus cooki, the “Coqui Guajon” that Norman discovered in December 2012, but there was a pleasant surprise. This expedition confirmed the presence of Eleutherodactylus richmondi, the “Coqui Caoba”, an IUCN critically-endangerd frog. According to Jan, whose Master’s thesis was on E. richmondi, there is only one other area in all of Puerto Rico where E. cooki and E. richmondi share habitat; Jan said this makes Icaco is a very special and unique location.
Erin Dahl, (who first came here two years ago with a team from University of Miami), Christopher Sanchez, and Danielle Ungermann all participated in the January harvest of mahoe trees from around the homestead. Andres, chainsawyer, and 3t, felling buddy, were happy to have the help of these three ready, willing, and able apprentices, and together, everyone trained and learned something in the essential art of directional felling, using cuts, wedges, ropes, and a come-along (a small portable winch usually consisting of a cable attached to a hand-operated ratchet).Gentle gasps of astonishment were heard as 65 feet tall trees fell, and fortunately, they all fell exactly where Andres designated. The team have been busy clearing the slash (the small twigs and branches), and depositing it back into the forest for nutrients and erosion control. Thank you Erin, Chris, and Danielle, we have really appreciated your stay with us.
Collecting Ausubo seedlings sounds like an easy task, but carrying full tree bags up and down forest slopes back to the homestead is demanding physical labor.
Our current Earthwatch Team assisted with this task on New Years Eve, and in one morning we collected 110 Ausubo (Manilkara bidentata) seedlings.
Ausubo (Manilkara bidentata), also known a balata, is a large evergreen forest tree that was probably the most important timber tree of Puerto Rico. It grows best in Puerto Rico on alluvial plain where it may reach the age of 400 years. Ausubo is extremely tolerant of shade. The strong and attractive wood makes it highly valued commercially an it is widely used in the tropics for many woo products. The tree is often tapped for its milky latex the source of balata gum. Although growth is slow, ausubo is planted for shade and timber.
Ausubo is one of the strongest and most attractive commercial woods in Puerto Rico. It is widely used in the tropics for railway sleepers, bridging, heavy construction, furniture, turnery, flooring, violin bows, and billiard cues. Its strength, high wear resistance, and durability qualify the timber for use in textile and pulpmill equipment. Its excellent steam-bending properties make it suitable for boat frames and other bent work.
The heartwood is light red when cut and turns to dark reddish brown when dry. The sapwood is whitish to pale brown. The wood is very hard, strong, fine textured, and heavy, with a specific gravity of 0.85. The wood rates excellent for boring, fair for planing, and poor for turning. It is difficult to air season and shows severe checking and warp if dried too fast. The wood finishes very well and resembles mahogany.

Planting endangered endemicsWe have an enthusiastic team of Earthwatchers here till the 6th January 2014. Continuing our collaborative project with Fish & Wildlife, we planted critically endangered endemic tree saplings, Styrax portoricensis and Cornutia obovata. To date 116 Styrax and 21 Cornutia have been planted in our spectacular secondary forest here in the Mira Flores mountain, better known as Las Casas de la Selva.
Vanderbilt Alternative Winter Break.
These students worked with Andrés and 3t on the reparation of a broken fence and gate and also completely pruned back an overgrown area that will house the new tree nursery. The weather was rainy for most of the time, so kudos to the team for staying on task and getting the work done. Norman Greenhawk and Magha Garcia Medina provided delicious food for the group, and they also got a night hike led by Norman. Thanks everyone for a week of super work. Now a few days of a Christmas break before we get ready for our next Earthwatch team arriving on the 28th December.
Thank You Vanderbilt Winter Breakers! We appreciate your time and effort in helping us with our goals.
