Review of Plant Science: An Introduction to Botany, by Catherine Kleier

Reviewed by Becky Strode

Plant Science: An Introduction to Botany (The Great Courses, 2017) is an informative and engaging course that you can watch on DVD or via digital download. Best of all: no homework and no tests! Plant Science comprises 24 half-hour lessons, and a 214-pp. course guide. The instructorCatherine Kleier, Professor of Biology at Regis College in Denversurveys the plant world, using photos, videos, computer animation, and her own obvious delight in the subject to make her lectures come alive. The result is intellectually stimulating and entertaining. After watching this course, you will look at plants with a keener eye and a deeper sense of wonder.

The first unit, “The Joy of Botany,” discusses what makes a plant a plant, looking at the cellular level. Subsequent lessons describe differences in the reproductive cycle of mosses, ferns, conifers, and flowering plants. Photosynthesis is explained using computer graphics to illuminate the complex biochemical processes by which plants turn light into energy and energy into sugars. Kleier discusses pollination, seeds, and fruits as well, and you will learn why a tomato is a fruit, and a strawberry is not!

Kleier also looks at plants from an ecosystem perspective, from underwater environments to deserts. She discusses problems caused by invasive species, concluding with a discussion of the promise and the potential dangers posed by genetic modification of plants. The range of potential dangers from genetically modified organisms (GMOs) that she identifies is wide and includes ecological, human-health, and economic risks. Kleier also describes new techniques on the biotechnology horizon that may enable scientists to make beneficial plants more resistant to disease without modifying their genes.

Plant Science can help a Master Naturalist contribute to our mission of environmental stewardship and education in several ways. The information you learn will help you better understand the plants you see around you every day. This will enhance your own enjoyment of nature and reinforce your desire to protect it. The course will also sharpen your observation skills, making you a more effective leader or participant during nature walks. You’ll know what to look for when you encounter plants, helping you identify them and place them in a broader ecological and evolutionary context. Finally, drawing from the course’s clear explanations and many examples of botanical concepts, you’ll be better able to share your knowledge and enthusiasm with others.

This class counts toward Master Naturalist continuing education credits.

Learning Opportunity: Scientific Collections in Conservation Research

A Talk by Dr. Gary Kupnick
Thursday, February 8, 7:30 to 9 pm
Green Spring Gardens
4603 Green Spring Road
Alexandria, VA 22312

Museum collections are remarkable and irreplaceable sources of information about biodiversity and the history of life on Earth. In addition to playing a critical role in scientific studies, they serve an important role in conservation biology, including documenting occurrences of invasive species; providing data on locality change due to habitat destruction and climate change; providing material for DNA analysis and conservation genetics; providing material for pollution documentation; and, serving as a means of locating possibly extinct species  This presentation describes several case studies to illustrate and explore the way scientific collections have and will continue to contribute to conservation research.

Sponsored by the Potowmack Chapter of the  Virginia Native Plant Society, this program is free and open to the public.

Review of The Humane Gardener, by Nancy Lawson

Reviewed by Ann Di Fiore

As a Fairfax Master Naturalist and Audubon at Home Ambassador, I am always on the lookout for books on native plant and wildlife gardening. The Humane Gardener (2017, 224 pp) offers insights on both topics, but what sets Lawson’s book apart from others is her emphasis on creating habitats that nurture all forms of wildlife. Interspersed with chapters on native plantings, creating habitat, and the benefits of decaying plant material are profiles of humane gardeners whose properties range from modest backyards to commercial farms.

Many of the principles Lawson lays out are well known to master naturalists: “Plant for all seasons and sizes” to address “diverse diners”; use “green mulch”—native grasses and groundcovers—rather than bark in between shrubs and trees to improve soil; choose straight species over cultivars; and don’t “love” –overwater and over fertilize—native plants.

Lawson urges us to be attentive to gardening activities that have tragic consequences for wildlife.  In a section entitled “Don’t Mow the Teenagers,”she warns us that mowing, pruning, and raking can cut short the life cycles of ground insects and other animals. Fritillary larvae, for example, crawl onto violet plants in early spring and, as Doug Tallamy puts it, “we murder them with our lawn mowers.”  Baby rabbits in hidden nests and other young animals are vulnerable as well.

When removing invasive plants from our properties, Lawson asks us to “triage” their removal to minimize adverse effects on wildlife that make use of these plants. Early blooming invasives may be the only available nectar sources to bees, fruiting shrubs like Amur honeysuckles may fill a significant part of a bird’s diet.

In The Humane Gardener, Lawson addresses an uncomfortable truth:  the wild creatures most gardeners want to support are songbirds and pollinators. Many other forms of wildlife we consider interlopers—enemies. She enumerates the cruelties inflicted by pest removal services, glue traps, even “humane” deterrents (predator urine, for instance, is captured from caged coyotes and other animals on fur farms). She advocates flexibility and a more generous perspective:  opossums and raccoons eat carrion, ticks, and slugs; rabbits devour dandelions; and moles and chipmunks till the soil, increasing its fertility.

In a world of shrinking natural spaces and biodiversity, Lawson asks us to reconsider our ideas of ownership and make room for all forms of wildlife.  Above all, she asks that we be conscious of the consequences of our routine gardening choices.  She promises that our gardens will be healthier—and more humane—as a result.

Family friendly volunteer opportunities: Restore habitat in Oakton and Vienna, 27 January

The Invasive Management Area (IMA) Program is hosting habitat restoration service opportunities on Saturday, 27 January, in Wayland Street Park in Oakton, and Borges Street Park in Vienna . See calendar for details of timing and requirements.

  • The minimum age to volunteer is 11. Please contact the IMA Coordinator for details.
  • Volunteers 13 and younger must be accompanied by an adult.
  • Students who need community service hours, please bring the form to be signed to your workday.
  • IMA workday forms must be received by noon the day prior to the event for weekday workdays, and by noon on Friday for weekend workdays.

The IMA Volunteer Program is a community-based project designed to reduce invasive plants on our parklands. This program gives volunteers an opportunity to connect with like-minded people while taking care of natural resources. Through IMA, you’ll protect the plants and wildlife of Fairfax County’s forests while spending time outdoors, meeting new people and restoring natural habitats.

IMA is more than just pulling weeds. It’s also habitat restoration and a long-term commitment to parks. Invasive plant species are difficult to remove and control, but with the help of IMA volunteers, undesirable non-native, invasive plants are removed and native plants are returned to the habitat. Native plantings take place in the spring and fall.

The IMA project began in 2006 with 20 sites. Since then, more than 35 acres have come under IMA management, and there are 40 active IMA sites. More acres have been treated and restored by contractors and staff.
