How You can Help Dragonflys

Want to help dragonfly populations? The Migratory Dragonfly Project is a citizen science project you can participate in. All you need is a pond or wetland to visit and a computer.

Participants monitor the timing, duration, and direction of travel of migrating dragonflies, and note any additional behaviors in a directed migratory flight such as feeding or mating. Photos or videos are strongly encouraged to aid in identification. When gathered across a wide geographic range and throughout a span of years, these data will provide answers to questions about which species are regular migrants; the frequency and timing of migration in different species; sources, routes, and destinations of migrants; and patterns of reproduction, emergence, and movement among migratory dragonflies along their flight paths.

Who’s Visiting Your Garden While You’re Not Watching?

My beautiful picture

I did a little experiment earlier this month and left our new CritterCam on for a period of five days, pointed at our backyard shed, to see what animals are visiting. The motion sensitive camera picked up seven visits from a possum, six birds, four skunk visitations, two rats, one raccoon and two house cats. I need to let the camera run for a longer period to get a better sense of what times of the day or night are the most active, but so far the hour of 2 am picked up the most activity (after the bars have closed on Sunset Blvd. perhaps?).

The pictures are showing what I think are mini wildlife corridors. Note the similar direction the possum and skunk seem to be heading.

The cat (which belongs to a neighbor):

And the raccoon (below) are also headed in the same direction.

That raccoon pic is another reminder for me to recheck my chicken coop’s fortifications.

And the rat is telling me to lock up the chicken food at night.

Reviewing these images has given me a less adversarial feeling about our mammalian visitors. They are just so damn cute, especially the skunk.

Next up in my CritterCam experiments will be to see who is visiting the bird bath. I’ll need some help from readers for that, since I don’t know my birds.

Are Bees Mammals?

Log hive.

Log hive.

This was the provocative question radical “apiculturlist” Michael Thiele posed at the beginning of his lecture at this year’s Heirloom Expo in Santa Rosa.

Thiele pointed out that bees:

  • Maintain a hive temperature of around 94°F/35°C
  • Have a low number of offspring, if you consider a swarm to be their offspring
  • Are nurtured by mother’s “milk” (technically sister’s milk)

These are all characteristics of mammals. Thiele inspiration is a book The Buzz about Bees: Biology of a Superorganism, by Jürgen Tautz who calls bees,”the mammal in a thousand bodies.”

Golden Hive.

Golden Hive.

Thiele’s next point was that if we think of them as a mammal than we’re going to have a different relationship with them. Practically, this might mean different housing. If a bee is a mammal what they live in becomes their skin and fur. To keep their hive temperature steady they need insulation, both in warm and cold climates. He suggested that the standard Langstroth box is too thin. Maybe they’d be happier in the two hives Thiele had on display, a hollowed out log or the insulated Golden Hive box (which had movable frames).

Thiele’s talk took a metaphysical turn when he said that we need to “go beyond the left brain” in our relationship with bees. He also, provocatively, suggested that we need to “know ourselves” before approaching bees. I took this to mean understanding our intentions, our goals, and our attitudes.

Back to housing. Langstroth was very much the product of a “left brain” industrial age whose point was the domination of nature. Given the problem bees are having, perhaps it’s time to strike a balance between the intuitive and analytical and, literally and figuratively, think out of the box.

016 The Urban Bestiary with Lyanda Lynn Haupt

LyandaLynnHauptBOOK-560x280

On the sixteenth episode of the Root Simple Podcast we interview naturalist Lyanda Lynn Haupt, author of The Urban Bestiary, Crow Planet, Pilgrim on the Great Bird Continent and Rare Encounters with Ordinary Birds.

During the podcast Lyanda covers:

  • The effect of the drought on urban wildlife
  • Invasive species
  • How to get along with wildlife such as skunks, possums, raccoons and coytes
  • The problem with relocating animals (except rats!)
  • Moles and gophers
  • Seeing raccoons during the day
  • Root Simple’s CritterCam
  • Possums!
  • Preventative measures
  • How to encourage wild animals and increase diversity by planting native plants and trees

Lyanda also answers listener questions about hawks, coyotes, and feral cats.

Lyanda blogs at The Tangled Nest.

CritterCam Reveals Yet More Rats and a Plea to Not Use Poison

My beautiful picture

Taking a cue from the NSA, I blew up and enhanced one of the images our CritterCam took over the weekend. It reveals two rats peeking out from under the shed.

It may be time to consider locking up the chicken feed at night. That and a little cleanup behind and around the shed are the only things I feel the need to do.

A rant on rat poison
Thankfully, the general public can no longer buy d-CON rat poison in California. Unfortunately, professionals still have access to even more toxic chemicals. These poisons have been linked to the recent illness of the magnificent mountain lion that lives in nearby Griffith Park. Check out the before and after photos to see what these horrible chemicals can do.

It’s my hope that the principles of Integrated Pest Managment, developed by a team of scientists at the University of California in the 1950s will gain even more traction. I met the daughter of one of the UC researchers who developed IPM. She told me that her dad had basically sacrificed his career to further the IPM cause. At the time, and to some extent to this day, there’s a lot of incentive to sell poisons.

IPM offers a balanced, common sense approach to dealing with critters like rats: observe, reduce habitat for the creatures we don’t want and increase habitat for predators, use barriers, use biological controls and use toxins as a very last resort.

Our own health and the health our planet demands a less toxic approach to pest management.

How many ladybugs can you find? The Lost Ladybug Project

We linked to this project in our last link roundup, but I though it deserved its own post. The Lost Ladybug Project is a citizen science initiative out of Cornell University asking people all over North America to identify and report ladybugs they see in their area, so that these sightings can be mapped and collected in a database. Apparently some sketchy things are going on with our ladybug populations (as if the whole bee thing isn’t traumatic enough) and they’re trying to get a handle on it. From their website:

Across North America ladybug species composition is changing.  Over the past twenty years native ladybugs that were once very common have become extremely rare.  During this same time ladybugs from other parts of the world have greatly increased both their numbers and range. This is happening very quickly and we don’t know how, or why, or what impact it will have on ladybug diversity or the role that ladybugs play in keeping plant-feeding insect populations low.  We’re asking you to join us in finding out where all the ladybugs have gone so we can try to prevent more native species from becoming so rare.

arggh…

But still….ladybugs!!!  Check out their website. It looks like a fun thing to do, for both kids or grownups. Part of the fun is learning to tell the difference between the different types of ladybugs. There’s lots of educational resources for homeschoolers and teachers. And yes, there’s even an ap for it.

It might be a little late in the year for the best counting, but I’m going to go out in the garden and see what I can find.
