LOCATIONS OF HIGH INTEREST: Hermosa Creek and South Mineral Creek AND the Poison Park Area of the Pagosa Ranger District

Weeds follow disturbance, such as wildfire. With cows grazing and humans, horses, and dogs travelling in the recently burned Hermosa Creek drainage, land managers and scientists expect to see an influx of invasive weeds.

SITES OF INTEREST

Poison Park North

Start with the large open meadows in the northern half of the area. These are our top priority for noxious weeds abatement. Smaller openings within the trees are less significant.

Poison Park South

Second priority will be the burn pile locations. Historically these have been associated with significant concentrations of thistles and other disturbed-ground loving species.

Lastly, if you have time, surveying the recently logged area in the southern half will be beneficial for our long-term monitoring
