In an effort to support restoration programmes, specialists are developing supplies of seeds and seedlings, maintaining gene banks and sequencing the genomes of indigenous trees and other crops. Their work deals with one of the problems that could block major restoration efforts in different parts of the world.
“ Where’ s the planting material going to come from? That’ s one big bottleneck, ” says genetic-resources specialist Rami Jamnadass.
Asia is arguably the region most neglected by global efforts to increase diversity in restoration and to study native species. Christopher Kettle, Biodiversity International’ s director for forest genetic resources and restoration in Rome, says that the need for infrastructure—things such as mechanisms for collecting and storing seeds, and nurseries to raise seedings—might be most desperate here because many trees are ‘masting’ species, which don’ t produce seeds every year. People need to be ready. “ Otherwise, you miss the boat, you lose all the seed you’ re got to wait another seven years, ” says Kettle. “ This is a really, really critical issue for restoration in Southeast Asia, because many of the most important timber species and tree species—the ones that will lock up the most carbon—they’ re all masting species.”
Climate change is a driving factor in the push to restore forests, but it also raises questions, such as where trees can thrive in the future. Climate change is also expected to alter relationships between trees, insects, diseases and other forest species. “ Insects that today are a minor problem may become a major problem if they can produce three or four generations in a year,” says forest ecologist John Stanturf. This remains a significant knowledge gap. “ We know enough to know that this is a concern, but we don’ t know enough about how to respond to it yet. That’ s a great area to be doing research.” So is soil, says Cindy Prescott, a forest ecologist at the University of British Columbia in Vancouver. “ If you don’ t look at the soil at the start, you can spend a lot of money and time putting in species that aren’ t going to survive there.”
With so much reason left to do, leaders in the field have been doing some soul-searching and although that restoration can be motivated by—and designed to meet—different needs.“When you talk about conservation or restoration, the first question has to be restoration by whom, for whom?” says Dansel Sanzen, a biologist at the University of Pennsylvania.
The question can have more than one answer. Much of the global funding for restoration is dedicated to developing it as a tool to mitigate climate change, notes Brancalion. “ But if you ask a farmer in Brazil if he or she is concerned about climate change, they would say, ‘No,I am concerned about water,’ ”he says. Their interests as stewards of the land need to be better integrated with those who have the money to support restoration.
That has been the strongest lesson of all for Chazdon. Restoration is about more than what gets planted in the ground,she says. “ Yes,it’ s about forests,but it’ s really about people.They are the agents of restoration.”
