ENTS:

The USFS issued a Directive in the past few days that will impact some
aspects of forest management on NFS lands. The Directive was issued on Feb 13 and
takes effect immediately.

Below are some of the definitions that appear for the first time that will
immediately become part of FS policy.

Definitions
Genetically appropriate plants. Plants adapted to target site conditions
(for example, has good establishment, vigor, and reproductive capabilities);
sufficiently, genetically diverse to respond and adapt to changing climates and
environment conditions; unlikely to cause genetic contamination and undermine
local adaptations, community interactions and function of resident native
species within the ecosystem; not likely to become (not natural or
inappropriate) invasive and displace other native species; and not likely to be a source
of non-native invasive pathogens; likely to maintain critical connections
with pollinators.

Invasive species. A species, including its seed, spores or other biological
material, whose introduction does cause or is likely to cause economic or
environmental harm or harm to human health (Executive Order 13112).
Native plant species. A plant species which occurs naturally in a
particular region, state, ecosystem and habitat without direct or indirect human
actions.

Noxious weed. A plant species designated as a noxious weed by the Secretary
of Agriculture pursuant to the Plant Protection Act of 2000 or by the
responsible State official. Noxious weeds generally possess one or more of the
following characteristics: aggressive and difficult to manage, poisonous, toxic,
parasitic, a carrier or host of serious insects or disease, and being
non-native or new to or not common to the United States or parts thereof.
Plant materials. Seeds, spores, parts of plants or whole plants.

Plant Material Specialist. An individual certified nationally to develop
and recommend revegetation, rehabilitation and restoration plans including site
preparation, species and source selection, seeding/planting specifications
and monitoring protocols.

Rehabilitation. Reparation of ecosystem processes, productivity and
services based on functioning pre-existing or existing ecosystems, but allowing for
adaptation of sites to specific current or future uses.
Restoration. Assisting the recovery of an ecosystem that has been degraded,
damaged or destroyed including the re-establishment of the pre-existing
biotic integrity in terms of species composition and community structure.
Revegetation. Re-establishment of plants on a site.
