HOW CLIMATE CHANGE IS CHANGING OUR PLANTS
|
SUNDAY - August 04, 2024, 1 - 2:30 pm
|
It has become obvious that our current land management practices are ineffective in sustaining the plants and animals that sustain us. Recent research has shown that 41 percent of the world’s insect population is in decline. Fewer insects would be devastating to amphibians, birds, fish, and reptiles that need these insects as a food supply. With global warming added to this scenario, it is like pouring gas on an already raging fire. In this seminar I will explore how the plants and birds are reacting to heterogeneous climate change and how we can modify this trend one garden at a time.

Instructor: Frank Niccoli

He has a degree in horticulture having studied at the Cal Poly, San Luis Obispo and at the College of San Mateo and also has a degree in Business Psychology and is an instructor in the Environmental Horticulture Dept at Foothill College.

California is one of the most biodiverse places on earth, and has an amazing array of plants that thrive in our gardens. By learning the seasonal rhythms of your own area, and the unique charms of the plants that grow naturally there, you can enjoy a bounty of bloom, berry and bark throughout the year. In the process, you’ll save water and enjoy a lush landscape that feeds local ecosystems. Attendees will receive a free packet of California native wildflowers with a long bloom season to try out in their own gardens.
