About the Kenal Peninsula CWMA

Why a Cooperative Weed Management Area?

Geographical areas are usually divided by numerous jurisdictional boundaries. State Parks, Federal Lands, Private property owners, Municipalities, and other agencies maintain and operate their respective managemnet obligations. Plants in general, including invasive weeds, do not recognize those boundaries. Picture a homeowner spending the first half of their summer (with considerable time and money) to eliminate all the dandelions in their yard, only to watch helplessly as a storm of windborne seeds from their neighbors yards blanket their lawn and start the new generation of dandelions. The "cooperative" component of a CWMA means that multiple agencies work together across jurisdictional boundaries to address an invasive infestation in its entirety within a naturally bounded geographical area. This ensures not only a high success rate for eradication, but also the most economical expenditure of funding, staffing, and other available resources. Reduce overlap, redundancy, and unnecesary replication. When we work to gether, we do more with less.

History and Founding Documents

The Kenai Peninsula Cooperative Weed Management Area (KP-CWMA) was spearheaded in 2003 by the Homer and Kenai Soil and Water Conservation Districts in partnership with the U.S. Forest Service - State and Private Forestry.  KP-CWMA gains a partner when an agency signs our Memorandum of Understanding (MOU), which formally outlines the intent of KP-CWMA and the role of a partnering agency.  In 2007, KP-CWMA developed a strategic plan that further fleshes out the organization's goals and objectives, management approaches, and invasives of highest management concern.

Primary Goals of KP-CWMA

1.  Prevent the introduction and spread of non-native, invasive plants within the KP-CWMA.

2.  Reduce the extent and density of newly established invasive plants to minimize spread and damage to natural resources (aka - Early Detection/Rapid Response).

3.  Implement the most economic, effective and safe control methods for priority  invasive species.

4.  Facilitate cooperation among those working to manage invasive plants on the Kenai Peninsula.

Prevention is the Best Solution

Prevention is the best approach to managing invasive species.  It takes much less time and money to prevent an introduction then it does to manage one that has spread across the landscape.   Prevention techniques include educating the public to identify and report invasive species of concern; implementing programs for invasive free straw, hay, and gravel pits; promoting weed-free products in construction and remediation; and working with greenhouses and nurseries to offer alternatives to popular invasive plant species.

Dog and horse owners could prevent the spread of invasives by using Alaska weed free straw and hay.

Invasive Plant Management List

After prevention, Early Detection and Rapid Response (EDRR) is the most cost-effective approach to managing non-native, invasive plant species.  EDRR involves constantly looking for invasives that are rare or that have yet to arrive on the Kenai Peninsula.  When a population of rare or new invasives are found, KP-CWMA and its partners culls that population to prevent its spread.  KP-CWMA has developed the managment list below to assist managers and concerned citizens in performing EDRR on the Kenai Peninsula.

KP-CWMA Invasive Plant Management List

EDRR species for the Kenai Peninsula CWMA are in the groups "New Invaders", "Potential Invaders to the KP-CWMA", and "Potential Invaders to Alaska" (see list above).  The group labeled "established invaders" are deemed beyond eradication on the KP-CWMA.  Regardless, "established invaders" are of high-concern to managers and the KP-CWMA seeks to prevent those invasives from spreading into or along fish and wildlife habitats, trails, and road systems.

A concerned citizen reported and the Cooperative Extension Service removed the only known patch of spotted knapweed on the Kenai Peninsula.  This is a prime example of EDRR.
