A Model for Land Stewardship
At Siglo, we’re not just planting koa trees—we’re building a demonstration forest. One that will show how you can establish a forest on land, that for hundreds of years, has been converted to cattle grazing. We’ve developed a number of research projects that will tell us how we can be more efficient and successful at planting trees. One day, we hope Siglo will be a model for other stewards and land managers to consider koa forestry as part of their own strategies.
