Habitat Connectivity

Connectivity Barriers are locations within connectivity linkage zones that most disrupt connectivity, which can be used to identify habitat restoration opportunities to improve connectivity.

Connectivity Pinchpoints are areas where connectivity could be severed with the loss of a relatively small amount of habitat. Habitat loss or degradation within these areas can result in a disproportionate adverse effect on connectivity, and therefore these areas may be prioritized for habitat protection.

Predation• Generally, research does not support predator (carnivore) removal for improving juvenile

or adult sage-grouse survival

– Conover and Roberts, 2017

• However, research suggests sage-grouse nest success decreases with increased raven densities

– GRSG nest success well below average at > 0.4 ravens/km2 (Coates et al. 2020)

– > 0.45 ravens/ km2 is the threshold where sage-grouse productivity falls below that required for population persistence (Coates and Delehanty 2010)

Wildlife Management. 74:240–248.

• Raven surveys in the Brother’s PAC during 2018 yielded 0.385 ravens/km2

– Plan to conduct raven surveys in future years to continue monitoring raven densities

• waiting on 2019 results

Prineville LIT Area

2017 2018

▪ Capture mosquitoes, test for West Nile virus (WNv), & assess sage-grouse use at guzzlers

▪ Trapping seasons for 2017, 2018, & 2020▪ 16 traps in 2017/2018, 4 traps in 2020▪ < 370 mosquitoes in 2017; < 800 mosquitoes in 2018▪ All WNv tests negative (2020 results forthcoming)

▪ Although not classified as summer habitat, sage-grouse still use areas where traps were deployed

▪ No traps deployed in Paulina/12-Mile PAC▪ Takeaways: hard to trap, hard to detect, low

probability that WNv is a stressor, but more information could be useful (paired between Brothers & Paulina)

• Harvest theory is based on compensatory vs. additive mortality

• Density Dependence– Can’t stockpile birds

• Harvest in Oregon well within compensatory mortality range– Annual harvest is typically ~3%

– Additive mortality occurs beyond 10%

• Oregon Sage-Grouse Action Plan– Action HNT-1: Maintain ODFWs harvest

policy of less than 5% of the fall population

– Action HNT-2: Do not authorize harvest within WMUs where the estimated spring population is <100 males
