Tidal Currents and Current Measurement at Race Rocks

The current at Race Rocks had just changed to a flood – it would be getting up to 6 knots in a few hours, so it was probably at about 5 knots at this time.

Adopt an Ecosystem


BACKGROUND: “Adopt an Ecosystem” involves using the internet as a means to get individuals and groups in other communities: provincial, state, national and international, involved in collaborating with others, and providing an educational resource while ensuring the stewardship of their own local ecological resources.

OUTLINE WITH POWER POINT PRESENTATION:
This 10 step outline presents the basic model of how to go about setting up an Adopt an Ecosystem Project in your school or organization.

 

THE PROCESS:
We are urging individuals, school groups and service groups in communities to establish internet files on a local natural area which they are able to document easily at a number of levels of scientific sophistication. This natural area may be a small corner of a school yard, a piece of coastline, a local stream or pond, or it could be an established ecological reserve or park. Valuable long-term baselines can be established with students of each year or individuals leaving a “digital legacy’ or a permanent on-line record which is available for other classes to make additions and updates in the future.
THE IMPORTANCE OF THE “PROCESS”

By involving individuals in the documentation and monitoring of their adopted ecosystem, a sense of “ownership” of one’s ecosystems and responsibility for their stewardship is experienced. In addition participants are encouraged to use technology to assist in the accumulation of valuable long-term ecological information which can serve as baselines for environmental impact decisions in the area, and as a valuable baseline on the area’s biodiversity.

OBJECTIVES: (The teacher and class may decide on setting their goals for this project, using only a limited number of the suggested activities.) After doing this assignment, students will be able to:

a) Design a plan and procedure for the creation of a local : “Adopted Ecosystem”

b) Use field methods involving quantification to document the chosen ecosystem with a baseline inventory.

c) Use a Spreadsheet program for the analysis and recording of locally collected data.

d) Set up a weather station for collection of weather data.

e) Construct a species list and/or taxonomy of the local organisms in the “Adopted Ecosystem”.

f. iNaturalist contributions Recently I opened an account on iNaturalist.com . I have been able to add many pictures of species taken around the Metchosin coast, as well as other locations. https://www.inaturalist.org/observations/garryf

It is a great idea to contribute to iNaturalist so by opening a free account on iNaturalist.com it  is a good way to do establish a baseline for organisms in your ecosystem and get professional assistance from experts for identification of species.  for instance for the biodiversity project the following entries are recorded by various individuals, https://www.inaturalist.org/projects/metchosin-biodiversity

f) Setup a website dedicated to the collection of resources relating to your locally adopted ecosystem.

g) Outline the Ecosystem Services and the value of the Natural Capital of your adopted Ecosystem.

PROCEDURE:. Identify the area and describe the ecological features that make the area unique, important or just representative of other surrounding ecosystems. Also indicate what your group intends to do with it.

2. You may indicate time lines for your goals, and even designate responsibilities to different group members in order to help you plan your strategy.

3. Establish a good “baseline inventory ” of what is there presently. Many ecological techniques are available to quantify organisms and their distribution. You may use our Transect Files as an example.

4. Establish a class project to provide a taxonomy of the species of your local ecosystem.

5. Include dated maps, databases, taxonomic inventories, checklists, photographs, videos or drawings to document your site. Open a project on iNaturalist.com  that enables you to enter photos of species and have experts help in making identifications

6. Begin monitoring the site for aspects of its structure and function. For structure: what living things are there, how they are distributed, what relationships or biotic associations exist. Also, the structure includes physical factors such as temperature, salinity, etc. –start gathering long term data, enter it into a database (such as excel), and save it to the internet site so that others can download and manipulate the data.

7.Download Google Earth and make a 3 dimensional image of the area with your ecosystem.

8. Search for historical and other recent maps or charts of your area. Include these as part of the information recorded.

9. If you have access to your own internet site, assemble the information on the site, let us know its location and we will provide a link to your site from racerocks.ca.

10. Establish a Project to list and value the Ecosystem Services and Natural Capital of your ecosystem. In recent years, we have started to acknowledge that “ecosystem services ” are something to which we must start paying attention as to fail to do so leads to a decline in quality of life:
This file explores that idea further and invites you to contribute to a new project : Defining the Ecosystem Services of Race Rocks. By looking at the model of such services developed for Race Rocks, you might also get an idea how you could choose a part of your own local ecosystem and do a similar analysis.

11. In the fall of 2005 we installed a Davis Weather Instrument at Race Rocks for real time monitoring of a number of meteorological events.

From this environmental data index page, you can see how we are developing pages for each environmental abiotic factor and interpreting how that factor is important in the ecosystems of Race Rocks. Many schools already have weather stations installed. Here are some examples from the Victoria area:

Pionosyllis sp. : Necklace worm– Race Rocks Taxonomy

Pioosyllis.

This annelid has only been observed a few times at Race Rocks, this photo was taken by Johan Ashuvud (PC yr 5) in 1980.

In Marine Life of the Pacific Northwest, this species is referred to as the “mystery necklace worm” .Detailed examination of the palps, teeth, cirri and chaeta are necessary for identification.

Below is another annelid from the gallery of images taken by Ryan Murphy in 2010 when he was Ecoguardian at Race Rocks.

Propane generators to be used as a backup system

Once into the tidal generating process, the engineers found out that these generator units were no longer necessary, so they have been removed

First Nations Burial Cairns on Great Race Rock Island

The configuration of the rocks in several stone mounds at Race Rocks are suggestive of First Nations use of this area for burials in the period AD 500. Investigation into sites on the lower part of Vancouver Island, have shown that over 400 such sites exist on the nearby Rocky Point area.
These sites have recently been the subject of a Master’s thesis by Darcy Mathews of the Anthropology Department, University of Victoria.

Darcy Matthews visited today to document these cairns.
