Resource Management - Shrublands

As shrublands mature, they eventually become shaded by mature trees growing among the shrubs. Shrublands must be periodically mowed to reverse natural succession and remove these trees. To do this, the refuge uses a variety of techniques including a piece of heavy equipment called a Hydro-ax. A Hydro-ax is essentially a mower for small trees. Operators slowly mow over the trees until they are mulched up. Because shrubs grow faster than trees, and areas that are mowed by the Hydro-ax are quickly recolonized by shrub species, providing valuable habitat for migratory birds and other wildlife that are dependent on this habitat type.
