Green Again Madagascar is a young non-profit aiming to reconnect rain forests in eastern Madagascar and collecting heaps of data in the process. Disclosure: Leighton Reid wrote this blog and is on Green Again\u2019s board of directors.<\/p><\/blockquote>\n

Matt Hill is trying to restore a rainforest corridor across eastern Madagascar. His motivation is that Madagascar\u2019s wet, eastern flank was once blanketed by a dark, rich forest festooned by bizarre plants<\/a> and teeming with unique<\/a> animals<\/a>. No longer. Over the last 70 years humans cleared almost half<\/a> of what was there in the 1950s \u2013 mostly for farming. Although the farming is often temporary, the forest rarely grows back. Weedy ferns and exotic trees find their way onto the abandoned farms and take hold \u2013 boxing out the Malagasy species.<\/p>\n

Some tropical rain forests can recover swiftly on their own, but not these. Eastern Madagascar is a strong candidate for hands-on ecological restoration.<\/p>\n

Matt is a middle-aged ex-pat and a self-described \u201cquant\u201d. His father was a math professor, and Matt followed in his footsteps, earning a degree in mathematics from the University of Chicago and subsequently a masters from UCLA. Before landing in Madagascar, Matt had a career on Wall Street analyzing large databases for Putnam. He retired early seeking a simpler and more natural lifestyle, which he found in abundance in rural northeastern Madagascar.<\/p>\n

I first met Matt in 2015 at Parc Ivoloina<\/a> \u2013 a zoo and forestry station near the port city of Toamasina. Clad in gym shorts and flip flops, Matt was buzzing between nursery beds shaded with bamboo slats and a laptop powered by a portable solar panel, where a local was entering data about tree survival and growth. Matt explained his tree planting system to me. At each stage, from seed to tree, he and his team measure plant performance \u2013 including survival, height, and diameter. Matt\u2019s team uses these data to quickly adopt methods that work and discard methods that don\u2019t.<\/p>\n

As he explained his tree planting system to me, I was impressed by Matt\u2019s attention to rigorous data collection \u2013 a preadaptation from his Wall Street career that serves him well in his new pursuit of tropical forest restoration.<\/p>\n

Starting a forest restoration program in eastern Madagascar<\/strong><\/h2>\n

Matt was introduced to forest restoration by accident when he was stranded for several days in Toamasina waiting for the wild, muddy road to Maroantsetra<\/a> to become passable. He visited Parc Ivoloina on a whim and learned about a recent wildfire. A local man had been making charcoal when his fire got out of hand and burned his own farm and 20 acres of a nearby forest. The experience moved Matt to begin growing and planting native trees on the burned land. This effort congealed into an NGO called Green Again Madagascar.<\/p>\n

From the start, Green Again has been a collaborative effort involving a team of local people. Jean Fran\u00e7ois Solofo Niaina Fidy is the head forester at Parc Ivoloina and president of a nearby village association. He initially advised Matt on the project and helped build local support. Many community members joined the restoration effort \u2013 growing trees in the nursery and planting them in the burned area. It is a steep learning curve. Many local people have only a few years of school and may not have held a pencil for some time. Matt teaches them to use GPS units, record data on datasheets, and enter it into an Excel spreadsheet. When the data do not make sense, they return to the field to take repeated measurements.<\/p>\n

The work is hard but good by local standards. Many locals make their living by breaking large boulders into gravel by hand, with a hammer. Others spend their days shoveling sand from the river into dugout canoes and paddling it to shore where it is picked up by road construction trucks. In contrast, locals who get involved in these forest restoration projects pick up transferable skills in horticulture, computing, and business management.<\/p>\n

Coping with wildfire (and learning from it)<\/strong><\/h2>\n

In early November 2016, Matt called me in a panic. There was a wildfire. His plantings had burnt to a crisp.<\/p>\n

Fires are common in eastern Madagascar, but this was a tragedy. To make a bad situation worse, the plantings that burned were an experiment that Matt was doing for a master\u2019s thesis at the University of Minnesota.<\/p>\n

In the ashes of his ruined experiment, Matt found a few survivors. He discovered that some native trees are resistant to fire. These survivors may lose their leaves and stem to fire, but they can resprout from roots.<\/p>\n

Importantly, Matt also learned that trees planted near the edge of plantings were more vulnerable to fire than trees planted in the center of a plantation. This is because the landscape outside of the tree plantations was more flammable than the trees inside the plantations. In particular, the thatch from a common fern (Dicranopteris linearis<\/a><\/em>) would catch fire\u00a0and burn for quite a long time.<\/p>\n

Green Again\u2019s recent projects have taken this new information on board. Now, new plantings are designed with the fire survivor species on the outside and the delicate species on the inside. Some new plantings are also more extensive, so that the edge-to-interior ratio is lower and less of the trees are placed in the riskiest spots.<\/p>\n

For good measure, Matt\u2019s team also includes some \u201cvulnerable\u201d tree plantings using the earlier techniques so that the next time a fire sweeps through one of the sites, Green Again will have tangible evidence about which strategy is the most fire-proof.<\/p>\n
