Biodiversity Galiano Island March Checklist

Spring is here! Help map the changes it brings to Galiano by photographing ten organisms living in a habitat near you.

To participate, all you need to do is: 1) Go for a hike and capture photographs of all ten species; 2) Start an account on iNaturalist; and 3) upload your observations to this Project.

Click here for a handy Field Guide to the species in question. Also check out the Active Pages for hints on when and where to find each one.

Be sure to include enough detail to help with the ID (multiple photos can go into one observation). Also be sure to place them on the map wherever you found them, and include a thing or two that you noticed or learned about each one.

When you're done, send a message to the Project Curator for your chance to win:

One year on Galiano Island: Timelapse Series 2015

I put this series together from a vantage looking northwest up the coastline of Galiano Island, on the Trincomali side.

There are a few gaps in the series—notably July, the driest month on island, as well as December, one of the wettest!

This series nevertheless captures well the spectrum of change that happens over the course of the year here.

People have remarked that the landscape changes very little—which partly owes to the dominance of coniferous forests and, here on the shoreline, the evergreen deciduous tree Arbutus. The vegetation reflects the mediterranean sub-climate of the island, which provides for mild, wet winters and cool, dry summers.

Still there are a couple of changes to note, which will also give some sense of the timeline:

1) Watch as the Ocean spray, the dominant shrub in the background of the shoreline, leafs out beginning in March and flowers from May–June. Its inflorescences go to seed, becoming sere and turning red in the July heat. Finally by September, leaf-fall begins. The leaves have all fallen by late November.

2) Notice also the brief snowfall in November. This frame is intercalated from 2014 (we didn't get snow in 2015); I took the liberty to include it just to add to the contrast of the series.

Full Moon Tide: August 28 2015

The tide under a full moon, August 28 2015.

My original intention here was to capture the tide at its main intervals, to create a place-based schematic of the intertidal for a field guide I was working on. So I divided up my day and the tide into four intervals, defining the lower lowtide line, the upper lowtide line, the midtide line, and upper tide line.

With these photos I was able to create a schematic of the cove, divided into the lowtide, midtide and hightide zones. I chose a good day for it! The tide ranged from 0.6 m to 3.1 m (2.5m).

It was fun scheduling my field work around the tide, playing in tide pools and going for hikes, then hurrying back to be sure I was there at the right time to snap the photo.

On Galiano there is a semi-diurnal tidal cycle with two high tides and two low tides occurring every ~25 hours. Those who know tides will know that the greatest volume of water (1/2 the total tidal flux) comes in during the middle 1/3 interval, according to the Rule of Twelfths. The pattern is perfectly evident in this time-lapse series.
