As part of the The Western Governors' Association (WGA) hosted a webinar on Rangeland Management Strategies, the speakers dug into some of the challenges and opportunities with reseeding.
There are a number of barriers, which vary across time and space, to native seedling survival. If soil freezes for even a 24-48 hr period, up to 90% of the germinated seeds can die. Alternatively, a couple of warm days in December can cause seeds to germinate. Precision restoration is key to perennial grass reseeding.
