The importance of reforestation… save forest means save our own place
You’ve heard it before: Deforestation is a major contributor to climate change. To put it simply, trees store carbon, preventing it from entering the atmosphere, which means there are fewer greenhouse gases screwing with Earth’s climate. And, broadly speaking, that’s true. Planting trees is good for the planet. But it’s more complicated than that. Research published this week took a finetoothed comb to the issue of forest management and reforestation. And the researchers found a major tangle: It turns out we’ve been planting the wrong trees, for a long time. And that choice of trees has actually been making climate change worse. And for nearly 250 years, forest managers have tended to prefer reforesting with more “commercially valuable” and fastgrowing species of trees, like pines, spruce and beech trees. Two of those three “preferred” species areconifers; more often than not, they’d be used to reforest an area where broad leaved trees once stood.
According to the researchers, almost 400,000 square miles of broadleaf forest have been replaced by conifers since roughly 1850. Choosing species for reforestation programs or community forestry in species-rich tropical rainforest ecosystems is a complex task. Reforestation objectives, social preferences, and ecological attributes must be balanced to achieve landscape restoration, timber production, or community forestry objectives. Here we develop a method to make better species choices for reforestation programs with native species when limited silvicultural information is available. We conducted community surveys to determine social preference of tree species and inferred their ecological suitability for open-field plantations from growth rates and frequency in forest plots at different successional stages. Several species, for which silvicultural data was available, were correctly classified as promising or unsuitable for open-field reforestation. Notably, we found a strong negative correlation between ecological suitability indicators and socioeconomic preference ranks. Only a single outlier species ranked very high in both categories. This result highlights the difficulty of finding suitable native species for community forestry and offers an explanation why reforestation efforts with native species often fail. We concluded that the approach should be a useful first screening of species-rich forest communities for potential reforestation species.
Around 50 people from state school and volunteers have participated in a tree-planting activity at the Ecologique Parque in Funchal. Jointly held by the Research Center at the Environment and Forestry Ministry’s Forestry Association of Research and Development, the program aimed to develop forests and reforestation after big a fire that was destroyed the area. It also aimed to spread awareness among company owners in the industrial zone to be more willing to provide plots of land for green spaces. The volunteers planted 480 trees, which comprised 5 species. “One person needs two trees to produce oxygen needed for his or her entire life. It’s important to plant trees both even in residential areas and industrial zones.
