HABITAT PROJECTS SPRING 2023
Join us this Spring to get Messy with Beaver Works! Be a beaver with us, and signup for one day and weekend long beaver planting projects on scenic eastern Oregon landscapes.
BEAVERHOODS - A WAY FORWARD
There's a lot of talk lately on how beavers can fix streams and the need for 'beaver reintroduction'. Many streams though are very broken, worsened by drought, without the conditions beavers need to settle and raise families. So we ask, in order for beavers to re-establish: What is it that beavers need to succeed, and how can we help them? BeaverHOODs provides an answer, and a path forward for natural beaver recovery.
Beaver, a keystone species, were nearly extirpated from eastern Oregon by 1900. Their absence resulted in the loss of natural processes which provided resilience in riparian ecosystems. The loss of resilience left these ecosystems extremely vulnerable to degradation by changes in land use that occurred during settlement.
While more modern land uses and management regimes in place since the initial degradation occurred may be less intense, they are often just enough, in the absence of the resilience generating processes, to prevent the recovery of processes which could restore resilience and ultimately beaver. With the addition of climate change as a stressor, riparian areas which may have eventually achieved a recent, degraded, and undesirable level of equilibrium are now likely on a downward trend again.
(Read on The Hudson Bay Company's Fur Desert Policy, by Jennifer Ott.)
Support beaver and the required components and processes that 1) sustain them and 2) allow them to function as keystone species. Prioritize these efforts in areas of their former range where they will have the largest impact on climate resiliency.
In short, remove human obstacles to beaver success.
Beaver Works Oregon makes this happen through these Focus Areas:
PROMOTING AND ESTABLISHING SUCCESSFUL BEAVER HABITAT
Beaver Works supports landholders and watershed organizations to prioritize restoration efforts, and the conditions necessary for beavers to be successful on the landscape.
SUPPORTING WORKING LAND STEWARDS ON WAYS TO SUCCESSFULLY SHARE PLACE WITH BEAVER
Recognizing that beaver habitat sometimes coincides inconveniently (and expensively) with human habitat, Beaver Works provides a beaver response team to advise landholders on practical, proven techniques and resources to address challenges (ex. damaged trees, flooding, blocked irrigation ditches or culverts, etc.) that may arise when sharing Place with beavers.
For those looking for learn more on how beavers change the landscape, we invite you to read Working Lands and Beavers (Stories from around the West) and Beaver Tales.
BUILDING AWARENESS OF BEAVER AS AN ESSENTIAL KEYSTONE SPECIES
Beaver works helps Oregonians to understand the benefits of beaver on the landscape as a keystone species - expanding the biological, ecological and historical narrative around Oregon's state animal. We help citizens understand and embrace enthusiastically that beavers can have an important, positive influence on the health of watersheds and our ecosystems.
Multiple generations of beaver need to be present in the same place at the same time. Mature beaver are needed to teach immature beaver, and to themselves engage in the dam building and other processes which sustain and alter their habitat.
- Translocation is rarely needed
Beaver need at least sufficient protection from compensatory levels of take from hunting/trapping; a level of mortality which would preclude population expansion.
- Education of local people, interest groups, land managers, natural resource agencies about alternatives to killing beaver, and their role and benefits
- Evolving local management regulations and land designations
- Changing state laws
There needs to be sufficient amounts and varieties of self-sustaining sources of food and building materials to sustain beaver families.
- This is not effectively quantified, but once it is, it could be modeled and a state-wide analysis could be conducted to see where habitat is lacking in priority areas.
- There needs to be enough water to sustain beaver escape cover throughout the year, to attract beaver to a stream reach, and to maintain the vegetation they require.
- Practices such as land use conversion, stream channel alteration which reduce water flows either individually or cumulatively to sub-critical levels should be restricted within priority watersheds.
FREEDOM FOR PROCESSES TO FUNCTION
Human/beaver conflicts need to be mitigated
- Processes by which mitigation can be accessed easily when it is needed (e.g beaver deceivers, plant caging, etc.)
- Education of role of beavers and mitigation opportunities.
- Laws and land management plans need to specifically designate sustaining actíve, multi-generational beaver populations as a priority and give substantive guidance to staff as to what that means in terms of on the ground management.
- Space to function: activities at levels which hinder the function or recovery of processes required for beaver should be restricted within riparian areas in priority areas. E.g. construction, road building, over-grazing, etc.
- Time: regulations should observe a timescale that recognizes that many processes that are involved occur on long-term cycles, and that the entire cycle must be allowed for, not just portions. For example, large parts of the productivity and ecological services rendered by beaver habitat modifications occur during periods of the cycle when beaver are absent from a site, when vegetation is regrowing, ponds have silted in and a meadow has formed; This area still needs to be protected for the value it is currently contributing, and for the eventual return of beaver to the site.
