| Whether or not you consider marine mammals to be a valuable part of an ecosystem, we have the unique opportunity of having an island close to a major centre of population which is a haulout habitat for five marine mammal species and a birthing habitat for three of those species. This is unique in Canada, and it is our responsibility to maintain that ecological integrity of the location as much as possible. The purpose of the ecological reserve is to protect as far as possible the entire ecosystem, including the seabirds, mammals, marine invertebrates, fish and algae. |
| Below we have some examples of the results of what we might call “Anthropogenic” or human caused disturbances from encounters of animals with motor boats. These are only the ones we see and document. No one knows what goes undocumented. Safe boating practises and speed reduction are needed in all areas around bird and mammal colonies. Regulations for all boaters within the reserve can be found in the regulations file. |

| In this video, you can see the results of what a motor boat can do when driven over an elephant seal. Male Elephant Seal Injured by BOAT propeller –January 2003 |
his file provides evidence of what can happen when boaters do not exercise caution. Over the years, we have picked up several baby harbour seals at Race Rocks which have been decapitated by careless boaters. The most recent ones in Pedder Bay are documented here also. | Regular observation and photographing of sea lions in 2009 has shown a number of horrendous injuries which are probably caused by collision with boat propellers. This file documents a number of those. |
Often the greatest ignorance about marine mammal viewing regulations is illustrated by the actions of recreational boaters. Such infractions of the laws are forwarded to the DFO Marine Mammal Division for follow-up.

| On the afternoon of February 15, 2009, these boaters were seen off South Rock, speeding in the ecological reserve and driving too closely, | They succeeded in stampeding the northern sea lions into the water. Being in that area they probably scraped bottom as well. |
On February 26, 2009 a vessel entered the reserve with excessive speed from the north just before noon. It stopped too close to North Rocks where some northern sea lions and harbour seals were hauled out. |
It then cleared the E. side of these rocks and again sped to the rocks on the SE side of Great Race. They did two passes of these rocks at this or closer distance, and then sped out of the reserve going north. |

From boat# 30K2923 an individual throws a baitfish to the sea lions from a few metres off the shore. Needless to say this was a first! Noon, September 30, 2009. |

The Problem with Drones
So far we have only had one instance of a drone being deployed over Race Rocks by a private boat in August, 2015. We would like to remind the public that because of the potential to disrupt wildlife, the only justification for deploying a drone in any Ecological Reserve would be for research purposes and then only under permit from BC Parks,
The Problem with Personal Watercraft

| The inevitable has happened. The personal watercraft was photographed on March 6, 2010 | These vessels are sure to increase in the area unless Federal regulations are brought up to date. | This sea lion was alert after two others had just been disturbed by the vessel and had jumped in the water. | In March, 2012 a pair of personal watercraft came through the reserve |
