Many factors make weed management on federal public lands an interesting challenge.
In September I was invited to join one of the Sierra National Forest Rangeland Management Specialists to explore a medusahead infestation in one of the grazing allotments she manages. The infested meadow used to be a homestead, though the only obvious reminder is the cluster of still-productive apple trees in the middle of an otherwise grass-dominated site. Pines and other conifers border the meadow, and a forest road divides the meadow into two parts. The portion uphill of the road is steeper and has more trees interspersed with the herbaceous vegetation, while the downhill portion is a more expansive, gentler sloping meadow. Due to the...
Thanks to the recent hot weather (already surpassing 90 degrees several days in a row), we are starting to see the lush green hills near Fresno transition into gold. The much-needed rain we received this spring could unfortunately create a problem in the coming summer: thick forage growth can quickly turn into fuel for fire season.
So, what does this have to do with weed management?
Before wildfire, weeds can be fuel;after wildfire, weeds can spread.
The main fuels in the valley and foothills are typically grasses. Even non-weedy grass species can be an issue if grazing livestock (and hardworking landscapers) can't keep up with grass growth before summer. Annual grasses are great...

Tarweeds, vinegarweed and turkey mullein are native forbs that stand out in Fresno and Madera County rangelands during the summer. Unfortunately, they aren't the most welcome. Horse owners despise tarweed because its sticky resin turns even brightly colored horses a grim muddy color; many rangeland owners dislike vinegarweed for its pungent smell; and turkey mullein, though common, is often disregarded until it looks like it has taken over dozens of acres overnight.
Although their native status may appease some landowners – they can provide food and habitat for some bird and pollinator species – most ranchers couldn't care less. Why, you may ask? These plants are poor forage for livestock, and most animals tend to...
