Two Top Speakers Highlight Botany Society's First Monthly Lecture

The Anza Borrego Desert Botany Society is fortunate to have 2 gifted speakers for our monthly lecture series this coming Monday (Dec 10) at 10 a.m.

Our first speaker is Kate Harper, known familiarly as Botany Woman. Kate has been a botanist in the Borrego area for years and is a principal contributor of Tom Chester’s excellent Web site, Plant Species of the Borrego Desert.

Kate will focus on desert adaptations. Hear her speak to learn which plant is the “King of Desert Plant Adaptations.”

Following Kate’s talk will be Dr. Chris McDonald, Natural Resource Advisor for southeastern California. Chris will discuss plants that jeopardize desert native plants. McDonald is an expert in invasive plants and will demonstrate how to recognize aggressive, invasive plants in the Borrego Desert and discuss what can be done to control them.

Dr Chris McDonald is the Inland and Desert Natural Resources Advisor for the University of California Cooperative Extension. His expertise is in managing plants in wildlands with an emphasis on managing difficult weeds.

After you have spent time planning and designing your California native garden and have selected the plants that you believe will work in harmony with your yard’s soil types and exposures proper installation is essential. Putting plants in the ground so that they can make best use of water in the ground and develop mycorrhizal networks with other plants will set them up for success in the years to come. Watering properly both at installation and afterwards will insure that your native plants have just what they need and not what they can’t use. Also, mulching your plants properly, without smothering the soil, will help protect their water resources, prevent weeds, and feed the soil.
This panel of experts will answer your questions about all of the above. The session will begin with some moderated questions curated from past workshops and then open up to an extended period of questions from the audience. Whatever you want to know more about on this subject--get your questions ready!
