• Some are immediate• Structures ‘settle’+ Hydraulic roughness
• Geomorphic Responses• Require high flows• Scour pools• Create bars

TYPES OF LIVING WITH BEAVER MITIGATION
I. Let’s not forget, they are pests!
II. Living with Beaver?III. Case Studies of Adaptively
Managing Beaver
IN SOME PLACES… THEY ARE A NUISANCE• In residential areas they can cause
flooding…• They often block culverts, which
can flood roads• They can chop down our
ornamental landscape trees• They can make a mess of irrigation
diversions
DYNAMITE DOESN’T WORK
• A common response to nuisance beaver dam building is to blow the dam up
• The dynamite is effective at breaching dam….
• But, the beaver are persistent, they can rebuild a dam in a night or two
LETHAL TRAPPING
• Lethal trapping is very common (and legal)
• Sometimes effective at temporarily alleviating problems IF all beaver are trapped out
• However, very hard to actually trap ALL beaver

II. Living with Beaver?III. Case Studies of Adaptively
Managing Beaver
LIVING WITH BEAVER STRATEGIES…• Is problem real or
perceived?• If real:
– ‘Beaver Deceivers’– ‘Pond Levelers’– ‘Caging’ trees– All require maintenance
• If those don’t work, live trap and relocation
BEAVER DETERRENT OR SCARE CROW
USFS APPROVED?
• From Cynthia Tait
SOME GUIDELINES FOR ‘LIVING WITH BEAVER• Provides basic
examples• Emphasizes ‘live
trapping’ translocation trapping entire family unit
UDWR – BEAVER MANAGEMENT PLAN
• One of most progressive plans in US• Specifically relies on beaver as a
restoration tool
UDWR BEAVER MANAGEMENT PLAN
• Awareness of non-traditional options is already increasing…
• Non-lethal options are being used throughout state
TRANSLOCATION • In Utah, translocation is
already allowed under UDWR’s Beaver Management Plan

II. Living with Beaver?III. Case Studies of
Adaptively Managing Beaver
PARK CITY STORY• Good old days of
traditional, undocumented beaver management
• Change of mgmt…• Beaver come back• Beaver cause
flooding problems• City removes
(traditional mgmt.)• But people liked
the beaver… and complained
• CONFLICT!
EXAMPLE OF HOW TO DO THIS…
Lays out an adaptive management response to the beaver problem…
SIMPLE DECISION POINTS – BY WATER COURSE
• Cheaper and more effective then just lethal treatment everywhere…
@ EACH DAM
ADAPTIVE BEAVER MANAGEMENT PLAN
• d
Hardware Ranch Beaver Management Plan• Worked with the
UDWR to develop a beaver management plan
HARDWARE RANCH BEAVER MANAGEMENT PLAN
• High quality beaver habitat
• Dam building has potential to flood ranch infrastructure and roads
FLOODING MITIGATED
• UDWR installed a pond leveler in 2013 to prevent flooding of bunkhouse
• Install another pond leveler
POND LEVELER FOR BRIDGE/DAM
• Install a beaver deterrent to maintain pond level
Hardware Ranch Beaver Management Plan
• Install a beaver deterrent to maintain pond level
MUST NOT HAVE BEEN MUCH GOING ON
HMMM. WHAT IS WRONG HERE?
SPRING CREEK WETLAND: WALMART LOGAN, UT
Working with Walmart Stores and the City of Logan to develop ‘Living With Beaver Strategies’
SPRING CREEK WETLAND: WALMART LOGAN, UT
• High quality beaver habitat
• Repeated trapping costly and ineffective
• Walmart manager wants to try ‘Living with Beaver’ strategies

EXAMPLES FREE FOR PLAGIARIZINGLays out an adaptive management response to beaver problems…
TAKE AWAYs• Beaver can be a real nuisance• Lethal control is generally
ineffective in long term• If you have a nuisance problem,
you have a nuisance problem• No such thing as a maintenance
free problem• Best to recognize the threats
they pose & develop adaptive beaver management plans
• Start simple (e.g. is it just a perception problem or real) & use lethal control as last resort
