The collection of plants, wildlife, minerals, and historical/cultural artifacts from WLT property by the public is not permitted.  Introduction of exotic plants and animals is prohibited. Introduction of native plants and animals is by permission only and on a case-by-case basis.  Scientific collection of plants, animals, prehistoric artifacts, and other inorganic materials is by written approval of the WLT only.  Specimens must be deposited in a public depository such as a museum or other academic institution.  WLT believes removal of natural materials can lead to damage in a variety of ways and that our lands and waters are primarily intended to retain as much of their natural qualities as possible.  We recognize that there are times when scientific collection is a valuable tool to further understand land and waters and their ecological functions.  We will grant written permission for collection that furthers our understanding of the land and waters that will be properly cared for, and made available to the overall scientific community.  Redundant collections may be required.  This information will be made available to WLT to aid in its further understanding of the resources under its management and care.
