Into the intensely compacted soil he planted 224 saplings of some 19 species of shrubs and trees timber, and guava and mulberry among other fruit trees. However, there are a number of issues associated with the use of planting that raise questions on public and private lands, including cost, quality of genetic stock, and the speed with which restored habitat can be obtained. Many restoration projects focus on individual sites, and dont take the surrounding areas or the ways they are used, managed and accessed by local stakeholders sufficiently into account.
