It's not always possible to take a plant subject back to the studio; and even when it is, there is a wealth of information that's important to capture about a plant in it's native habitat. We'll discuss supplies to take into the field; drawing/painting outside; nature journaling; and tips for capturing the information you'll need later in the studio.

About our Presenters


Harold Koopowitz is a Professor Emeritus at UCI. He taught Conservation Biology, among other ecological topics, and has published widely on conservation.

Ellie Tu, after a career in Taiwan and France as a product designer which requires mostly digital rendering, found a long-lost love of painting plants by hand. She is a volunteer at the demonstration garden and nursery in Channel Islands National Park, for whom she also illustrated the native plants guidebooks.

Lesley Randall has been drawing plants for several decades. She has prepared scientific illustrations for several floras and numerous journals as well as participated in botanical art exhibits in the US and abroad. She works primarily in pen and ink.

While accuracy is the most important aspect of illustration, she finds pen and ink to be an elegant art form. It is a wonderful way to define a characteristic and describe a form.  It is also quite versatile depending on techniques used it can be subtle or bold. In recent years, she likes to pair it with watercolor and colored pencil to create bold vibrant art.
