Au Naturale

Lasqueti is quite sparsely populated and lies in a rare ecosystem type - the Coastal Douglas Fir zone. Our famous herds of feral sheep, along with the unique history of settlement have resulted in an ecology and natural environment with its own character.

Many, professional and ametuer, have taken a keen interest in Lasqueti's Ecology, it's Natural Environment, its Flora and Fauna, its Ecosystems - in short, its Natural History. But not much of this wealth of information has made it on the site yet - what has, you'll find here. If you have something to contribute in this regard, Contact us.

Invasive Plants

Not every plant sold in a nursery makes a good choice for your garden or landscape. Some non-native plants find wild success in Lasqueti's climate and soils - so much so that they can spread uncontrollably, pushing out more sensitive species. Many of the following are mentioned at www.bcinvasives.ca as being invasive plants in BC. If you know of others, contact Terry at 8501. I am slowing working on this project , so forgive the incomplete information.

Lasqueti Butterflies

This site is for butterflies that have been seen and identified on Lasqueti Island.Over several years I have sent photos or butterflies I've found dead to Cris Guppy, the author of Butterflies of British Columbia, for positive ID and for his record keeping. Many thanks to Cris for his help and encouragement.

The information and photos are intended to help anyone who wants to get to know these local residents better and to appreciate their grace and beauty. They have truly marvelous lives and life cycles.

If there is no photo credit, I took the picture on Lasqueti. Otherwise, the photographers are credited, and the photos are used with permission.

BUTTERFLY CONSERVATION: The biggest threat to butterflies is habitat loss: to urban development (pavement, manicured lawns), intensive agriculture, logging (for a few species), and overgrazing by cattle and sheep. On Lasqueti we can encourage and preserve natural areas -- especially forests, sheltered forest glades, wet places and streams, brushy areas, and patches of nettles, willow, and alder, which are the host plants for many local butterfly species.

It is also important to avoid completely the use of herbicides and pesticides, including and especially Bt, which is widely sold as a mild way to control some pests but which is deadly to the larvae of all butterflies and moths.

If you do want to plant a butterfly garden, be sure the seeds you are sowing are for the butterflies that are or could be here. Most seed mixes sold for this purpose are primarily for the butterflies in other geographic areas. I have found that a general mix of flowering herbs, shrubs, annuals, and perennials seems to attract a lot. Host plants for the larvae are at least as important for species survival as nectar-producing flowers. Butterfly gardens are more for our pleasure at seeing the adults (I have seen 25 Painted Ladies at once on Lasqueti, in a large planting of lavender.).

Raising purchased butterfly larvae, or releasing butterflies at a wedding or other event, is not a good idea, as it puts non-native butterflies, or non-resident populations, into an area -- the same as Atlantic salmon escaping from fish farms into Pacific waters.

Moths and butterflies are categories of the insect order Lepidoptera, which comprises possibly a million species. Generally, butterfly antennae are thread-like, with a small club at the end. Moth antennae usually lack clubs and resemble either threads or feathers.

NO ROYALTY ON LASQUETI! People will sometimes refer to the "Monarchs" on Lasqueti, mistaking the two species of Swallowtail butterflies that are here for the famous and widely pictured Monarch butterfly. Swallowtails are white or yellow with broad black tiger stripes. Monarchs are orange, with thin black lines in a stained-glass pattern, not stripes. While it would be lovely to see these master-migrators on Lasqueti, they have only rarely been recorded anywhere on the coast. Their primary range is to the east or the south of us.

WATCHING BUTTERFLIES: Mostly, to watch butterflies, you just have to go to a likely habitat, in season, after the day's sun has warmed things a bit, and sit and be patient. You will notice many as you walk on the roads or woodland edges or in fields, or as you garden. A pair of close-focus binoculars is a wonderful tool for butterfly-watching. A few years ago these were out-of-reach expensive, but they are now being made for the popular market. If you are shopping for binoculars, be sure to check the focus range. If the smaller number is 2 metres or less, you're OK for butterflies.

I have seen butterflies in the usual haunts in and out of the garden, and also crossing bays and between islands. Since they sip water and minerals from various places, they may also be on beaches and tideflats, on piles of old seaweed, and on mud and animal dung. (Note: A greenhouse with the doors open can be a great butterfly-catcher, but if your greenhouse is trapping them, it is essential to check a couple of times a day and catch and free them. Gentle handling is fine, just be sure not to squeeze the body. We were catching so many, and not always finding them in time, that we now net the doorways.)

The more you observe, the more you'll see: courtship, mating, egg-laying, larvae, and pupae, as well as the beauty of the adults. If you notice an adult flying around host plants, some time spent watching could reward you with the sight of egg-laying, and then you will know exactly where to look later for larvae and pupae.

To learn more, in addition to watching, take a look at these books and websites:

Butterflies of British Columbia by Crispin Guppy and Jon Shepard. UBC Press, 2001. A big, definitive book.

The Butterflies of Cascadia, by Robert Michael Pyle. Seattle Audubon Society, 2002. A useful field guide to the butterflies of Washington, Oregon, and southern BC. Great photos, lively writing.

http://efauna.bc.ca Photos and extensive information about all types of animals in BC. Complete and easy to use. (There is a comparable eflora site for BC plants.)

www.butterfliesandmoths.org One of those US sites that define "North America" as stopping at the 49th parallel, but there are no butterflies in southern BC that do not also occur in northern Washington. Good photos.

Food self-sufficiency -- Eating well out of your Garden -- Tips on Local Gardening

A series of articles on year-round eating from the garden, by Sue Wheeler

These articles, arranged by month, are intended to pass on information to help us become more food self-sufficient by eating well out of the garden all year round. I will include tips I've picked up from my own and friends' experience, plus information I've run across that I haven't seen elsewhere. I don't plan to include info that is widely available in garden books and articles, such as how to grow squash or potatoes or other crops that are harvested in Fall and stored.

"Winter gardening" is really spring and summer planting for winter eating. It requires planning to be sure there is a place in the garden for the overwintering crops to go in at the right time. For example, when you plan where you'll plant carrots, allow space for spring planting of the summer carrots and also summer planting of the carrots that will be left in the ground and harvested through the winter and into spring. A bed that had the earliest peas and lettuces will be finished in time for the overwintered cabbages, broccoli, and cauliflower. I reserve a spot from the beginning of the season for kale and chard, which need to be seeded in the garden before any of the early crops are finished.

A good source of information is Linda Gilkeson's articles about winter gardening on the coast, which can be found at

http://www.saltspringenergystrategy.org/food.htm

Linda also has an excellent book, Year-Around Harvest, which can be ordered from West Coast Seeds, Salt Spring Seeds, at local bookstores, or through her website, www.lindagilkeson.ca

Another recommended book is Eliot Coleman's Four-Season Harvest, available at the regional library (www.virl.bc.ca)

Here is a table of what to plant when on Lasqueti (adapted from Linda Gilkeson's "Salt Spring Planting Dates" in her book Year Round Harvest)

WHEN	WHAT TO PLANT
Feb. or March	Leeks
April-May	Celeriac, parsley, leeks, chard
Early June	Brussels sprouts, carrots
Mid- to late June	Purple sprouting broccoli, winter & over-wintering cabbage, parsnips, beets
Early July	Rutabagas, endive & radicchio, kale, kohlrabi, overtintered cauliflower
Late July-early August	Arugula, fall & winter lettuce, mizuna and other Asian greens, collards, kale, daikon and winter radishes, spinach, corn salad, basil (for transplanting to pots for a windowsill indoors in early fall)
Early August Late August to mid-September	Over-wintered onions Corn salad, cilantro, arugula, winter lettuce
early October	Lettuce and spinach in greenhouse

April 2009

This week's article from Linda Gilkeson's email list is about hardening off seedlings. You can get on this list by emailing Linda at info [at] lindagilkeson [dot] ca. She lives on Salt Spring, so her tips are directly useful for us. You can read all her past articles at the link she cites below.

Quoting Linda:
How you harden off tender seedlings can have a long term effect on the crop. Hardening off is the process of reducing the growth rate of seedlings by exposing them to cooler conditions and less water and fertilizer. As their growth is checked, plants accumulate food reserves, which they can use to produce new roots faster when they are transplanted. Hardening off also thickens the cuticle and wax layers on leaves, which helps plants to withstand wind and weather and protects leaves from sunburn.

Some plants can be hardened off to withstand frost, including the cabbage family, lettuce, most greens and onions. If transplants plants are too large, however, exposure to temperatures under 5-10oC for more than a couple of weeks can make some of them send up seedstalks.

The tricky thing is that there is a disadvantage to over-hardening plants. Such plant are slow to begin growth and may never really recover, resulting in lower yields and later maturing crops. Transplants suffering from uneven watering, from being rootbound or chilled become over-hardened. Plants for sale have usually been hardened off by the time they reach the market so they become over-hardened if they hang around too long before they are set out. [Find out when your local nursery brings in new stock, buy your transplants the day they arrive and plant them out immediately or else pot them on]. Home grown seedlings that were started too early suffer the same fate if they end up being held too long in small pots.

Hardening off is least helpful for tender plants, such as tomatoes, peppers, cucumber, melons, squash, and celery. Ideally, you want to time the seeding date for these so that transplants reach the right size to go into the garden just as the weather becomes warm and stable (good luck with that!). Such tender plants are better off being started later rather than earlier so they don’t experience a check in their growth. In any case, if seedlings are becoming rootbound and the weather still isn’t warm enough to put them out, they should be potted in larger containers and kept in.

Hardening off for tender crops mainly means getting them used to direct sunshine. Tender plants that have been started under glass can be seriously damaged or even die from sunburn if suddenly moved outdoors (really!). Sunburn damage on cucumbers and squash (the most susceptible group) appears as light tan spots and blotches on leaves and stems.

What to do: Gently harden off transplants you have grown by gradually exposing them to direct sun and outdoor conditions. Starting with an hour or so the first day, set them out for a longer period each day, taking about a week to get them used to a whole day outdoors. Move them indoors if nights are cooler than normal. Once they are set out, keep sheets of plastic, floating row cover, cloches or other covers handy to protect transplants from an late cool spell.

May 2009

WHAT TO PLANT THIS MONTH: It's not too late to plant leeks, for harvest through the winter and into next May. Parsley planted now will last over the winter in the garden, barring three weeks under heavy snow (and even then it did come back from the roots) And it's not too late to start celeriac indoors, for transplanting into the garden when it's truly warm later in the month. It will last through next April.

First week of July

This week: last chance to plant beets, carrots, and rutabagas for late fall/winter harvest. If it's hot, a cover of burlap or newspaper will help keep the seedbed moist until the seeds sprout (Remove this as soon as they have sprouted).

This is also the time to plant seeds for overwintered cauliflower, to be harvested next spring. If you didn't get seeds for this crop this year, make a mental note to get them when you order seeds next winter. It's the sweetest cauliflower you will ever taste, and great to have at that time of year.

Look for and prepare a place where you will be able to sow hardy greens in a couple of weeks-- chard, kale, arugula, spinach, Chinese cabbage and other Asian greens.

Early August

The arrival of August shift us into the next phase of planting for winter eating. August 1st is the halfway point between Summer Solstice and Fall Equinox-- Lammas, in the Celtic and old British calendars, a harvest festival in which bread baked from the first wheat harvest of the year was blessed. Bread blessings sound good to me! The shortening of the days means that seed can be sown for overwintered onions (Onions are sensitive to day-length and might bolt to seed too early if planted sooner). Walla Walla is the main variety grown in this area-- a large, delicious onion that will be ready for harvest around July 1st next year (OK, it's not exactly winter eating, but it does fill the gap left by the last of the stored onions, before next year's crop will be ready). Seed a few rows in any spot in the garden, cover with a little protection against the worst winter weather, then transplant next spring into that year's onion area.

You can sow all the Asian greens now for fall harvest, plus fall and winter lettuces, arugula, kale, winter radishes, spinach, scallions and corn salad. Corn salad, also known as mache ("mosh"), is especially hardy, and works well as a cover crop as other things get harvested.

Tips for seedling survival in hot weather: If your soil dries especially quickly, so that daily watering is not enough to germinate seeds, try covering the seeded area with cloth or a couple of layers of newspaper. Check each day and remove as soon as the seeds have sprouted. After this, to shelter the babies from too much sun, I've been using upturned bedding plant trays, those lattice-work black or grey plastic trays that a dozen or so small pots come in from nurseries. They let in about 50% of the light. They turn up at the Free Store, or maybe a neighbour has a few spares, if you don't have any. Shade cloth would work, too.

Early September-October

The best time to plant for fall and winter eating may have just passed, but if you haven't been able to do it yet I'd suggest going out there right now and sowing some lettuce, arugula, spinach and corn salad, especially if you have room in the greenhouse or a cold frame or any other place you could shelter after the weather turns. It is probably not too late to plant cilantro, which is surprisingly hardy-- one Lasqueti gardener had hers survive outside last winter, with no protection, through all that snow and cold. If you can get transplants from a neighbour, or find plants for kale, Asian greens, or lettuce at a nursery, that would put you a couple of weeks ahead of direct seeding.

Through early October you can sow lettuce, spinach, arugula, and Asian greens, under a cold frame or in a greenhouse, that will germinate and stay small through the winter and begin to grow quickly when the days lengthen in February, giving you salads in the early spring, before you need the greenhouse for tomatoes etc. Whatever you do, be sure to get cover crops on the bare patches in the garden as they appear after harvest. If you are able to do only one thing for your next year's garden, this is the best. Make a note of the fall and winter crops you wish you'd gotten seed for this year, for next year's seed ordering. The whole schedule of what to plant when is on the main page of the Zero Mile Diet site.
