Sandy Lake and streams in Dec 13, 2018

On December 13, I repeated a set of observations on pH (a measure of acidity) and EC (electrical conductivity, a measure of salt content) that I had made just over a month ago (Nov 8, 2018) on streams entering Sandy Lake via culverts at the southwest corner.

The lake was frozen solid. I am told it is the first time it has frozen over before January in about 20 years.

Electrical conductivity of Sandy Lake itself has increased over the years:

Thus Dec 6, 2018: A natural history perspective of the forests, wetlands and surface waters of Sandy Lake (Bedford) & Environs

Posted on November 19, 2018 by admin

Place & Time: 7pm at 45 Connolly Rd #206, Middle Sackville (the SRA offices)

Description: As a volunteer contribution to the efforts of the Sandy Lake Conservation Association to protect the ecological integrity of Sandy Lake and environs, David Patriquin conducted extensive observations on plant communities and surface waters of Sandy Lake and environs (including the Jack Lake lands and lands around Sandy Lake and Marsh Lake) over the interval June 14, 2017 to the present. His objectives were “to describe ‘what you see on the ground’, identify significant ecological attributes of the area, and make some assessment of existing or potential threats to the ecological integrity of the area.” David will provide a virtual tour of Sandy Lake and Environs and present his major conclusions about what he now sees as a major ecological and recreational asset for HRM.

David retired from his position as Professor of Biology at Dalhousie University in 2008. Since then he has been active several natural history and hiking groups with a focus on the Chebucto Peninsula.

Friday September 14th, 2018: Sackville Rivers Association dinner & auction

Posted on September 10, 2018 by admin

“Dear Friend:

“Last year, community contributions to the Sackville Rivers Association’s (SRA) Annual Dinner and Auction helped us raise over $8,000 for the improvement and conservation of the Sackville River and surrounding watershed.

“The SRA continues our mandate of conservation, including in-stream habitat improvements at various locations throughout the watershed, fish stocking, and river clean-ups by volunteers of all ages. We have continued improvements to our Bedford-Sackville Connector Greenway trail that now stretches from Bedford Basin to Lower Sackville and is used by thousands of walkers, cyclists and runners and are currently constructing phases 2 and 3 of Section B of the Sackville Greenway from Glendale Drive to Sackville Drive along the Little Sackville River.

Multiflora rose, an invasive that crept up on us in Halifax, NS

Posted on August 9, 2018 by admin


Rosa multiflora climbing over trees in
Lower Sackville, Jul 7, 2018.
Click on photo for larger version.

A colleague from my Dal days had a question for me: is the white rose I have in my yard an “invasive”?

He had been cycling the Grand Pre to Blomidon route in The Valley and had seen a white rose climbing over trees. He was already battling what looked like the same species growing over his garage from a neighbouring property and had another, smaller plant in his own yard. Is it “invasive”? Should he take it out?

These are question others in the Halifax area may be asking. I can’t offer definitive answers – any discussion of invasive species, even amongst ecologists*, – can be surprisingly intense – but I can offer a perspective as I have been following the advance of multiflora rose (Rosa multiflora) into the Halifax area for a while. I have also made some efforts to control it in a few areas. Continue reading →
