The Problem with Pollinators

On the heels of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) report about the potentially catastrophic worldwide decline of pollinators, I’d like to offer some  gentle reminders to home gardeners and all others concerned about the health and maintenance  of our food supply and the natural world as a whole.   The report paints a dire prediction of decline and extinction of  pollinators–honeybees, wild bees, butterflies and moths, and all other pollinating animals who play a vital role in production of managed crops and propagation of native plants and trees.  I certainly hope that this report will bolster efforts to support educational and research organizations in their work toward encouraging local, state and federal authorities to set aside land for prairies, native grasslands, and wild space in general, and to manage that space in appropriate and sustainable ways.

There are simple practices that the home gardener can engage to assure a safe haven for pollinators and all wildlife in general:

Refrain from pesticide and herbicide use.  Not only will abstaining from chemicals save you money and time, but usually, these chemicals create more problems than they fix. If you plant appropriately for your region, the need for chemicals in the garden decreases or disappears.

Use native plants!  There is no easier way to attract and sustain wildlife than to plant native plants–for pollinators, birds, bats, reptiles–every native critter will visit when their preferred food source is available.   Where native plants are hard to find, plant non-invasive, well-adapted pollinator-friendly perennials and annuals.   When replacing shade or ornamental trees, plant native trees; a large native tree is life-giving in so many ways.  Your locally owned nurseries and Agricultural Extension Agent offices and websites are excellent sources of information on appropriate plants.

Allow some “nature” in your garden.   It’s perfectly fine to have a few leaves, branches, and garden detritus  in your garden for critters to use as cover and for nesting purposes. The 1950’s swath of lawn and scraped garden are so…yesterday.  A water-hogging, sterile lawn coupled with a few pristine, non-nectar producing plants (usually sold at big box stores) and placed solely at the foundation of a house, are antithetical to how nature exists and functions. Birds, mammals, amphibians, reptiles, and beneficial insects have no place to live and thrive in that kind of “garden.”

Your garden doesn’t have to be wild  to attract wild.  No matter what garden style the gardener appreciates and aspires to, incorporating plants that are beneficial to wildlife–those providing nectar, seeds, berries, and cover–is easily accomplished as time and budget allow. Whether in a formal or a cottage garden style–or anything in between–using wildlife-friendly plants, pruning after seed production, and refraining from chemical use is the ticket to a successful and life-nurturing garden.  And isn’t that what gardening and gardens are all about?  The creative endeavor of nurturing and sustaining life and beauty.

Provide water!   As simple as a bird bath or as complicated as a series of ponds with attached streams and waterfalls, water is a requirement for life and should be a part of any garden.  ‘Nuff said.

There are already places in the world where, because of mismanagement of land and misuse of chemicals, there are no pollinators available.  None.  They’re all dead.  Crops grown are hand-pollinated by people.  Surely this is not what we want worldwide, but that scenario is exactly where we are headed.  We can choose a different route and it doesn’t require great inventions or new technologies, but instead, thoughtful gardening and agricultural practices, as well as the political will to acknowledge and edit the environmental costs of industrialization.

Please consider the health of your local environment when you plan a garden.  Support private, municipal, and federal efforts to set aside land for wildlife.  Our survival, as well as the maintenance of the remarkable and diverse biology of the Earth, depends upon our acting NOW.  This is a solvable problem.  Let’s solve it.

Pollinators are our friends and co-workers.  It’s in our interest to do right by them.

Look Who’s Moved In!

For several weeks now, I’ve heard the trilling of an Eastern Screech Owl, Megascops asio, in and around my back garden–either at dusk or in the wee hours before dawn.   Last week, I saw two owls sitting together just after sundown in my Retama, Parkinsonia aculeata, tree. Until then, I’d only spotted one at any particular time.  Early this morning, noticing an upset and noisy Blue Jay cawing into the owl nest box, I spied this sleepy and probably annoyed Screech, settled cozily in his/her box.

It’s a nice neighborhood  and I hope this couple raises their little family successfully, as has happened for most of the last 8 years.

All the best to my new neighbors!

Right on Time

Winter is almost done and was not only late, but a rather ill-mannered no-show in my garden this year.  Here in Central Texas, the trees are flowering and leafing out with abandon, seemingly racing one another to full-fledged foliage.  Even so, the only plants that are weirdly early in my gardens are the Shumard Oaks–they don’t normally flush new growth until the very end of February or beginning of March.

But like an excellent and welcomed dinner guest, the Golden Groundsel, Packera obovata, is right on time in preparation for its flower showOne of our earliest bloomers,  the bloom stalks have arisen and will brighten this shady area in the next few weeks.

While the brilliant flowers are stunning,

…the foliage of this tidy, woodland wildflower is what I find most appealing about this North American beauty.  Evergreen and ever-lush, the plant forms a colony of finely serrated, ovate leaves and those make up the  “staple” foliage of the plant, year round.

As the plant prepares for flowering, the foliage connected to the bloom pedicels develops a more fern-like, deeply serrated character.

My colony of Golden Groundsel hasn’t spread much in the  5 or 6 years that I’ve grown this plant and I’ve had no good luck in transplanting newer clumps-with-roots to other places.  But it’s a happy and hardy filler in this spot,

Perhaps the blooms will be up and running in time for Garden Bloggers’ Bloom Day in March!

In celebration of February foliage, thanks to Christina’s lovely Creating my own garden of the Hesperides.   Check out her Garden Bloggers’ Foliage Day meme for a look at foliage from many gardens.
