Old Growth and Birds, Mason Bees And Snorkel Survey (30x3)


Uitzenddatum: Okt 25, 2018

Master gardener Ron Spendal has taken it on himself to learn more about mason bees, a native pollinator and backyard favorite. Every year, volunteers snorkel Northern California’s entire Salmon River Watershed to count, and hopefully protect, its spring Chinook. And scientists are finding that certain songbirds are thriving in Oregon's old growth forests, even as they're declining in numbers elsewhere.
