As I write this post, we are in the midst of a “Nature Challenge” to residents of Halifax (HRM, Halifax Co)

“Help put Halifax Regional Municipality on the global nature scene! On April 26-29, 2019 over 165 cities across the planet, from Columbia to New Zealand to Calgary Alberta, will compete for the most Biodiverse City, and we need your help. Whether your an avid naturalist or a dog walker, everyone can participate: it’s easy, fun, and will encourage you to get outside. We will be using the iNaturalist digital platform to record observations, under this project.

Please keep an eye out for the “Hemlock Vampires”

There is a recent posting on iNaturalist of a putative occurrence of Hemlock Wooly Adelgid (HWA), aka the Hemlock Vampires, in Hants Co.

If confirmed, the Hants Co. sighting would be the first outside of Digby, Queens, Shelburne, Yarmouth and Annapolis counties in SW Nova Scotia.

Regardless, please keep a watchful eye on hemlocks in the Sandy Lake (Bedford) area – in fact on all hemlocks in NS – and photograph and report anything that looks like HWA to the Canadian Food Inspection Agency &/or ISANS &/or Nova Scotia Lands and Forestry – Donna.Hurlburt@novascotia.ca (Wildlife Manager, Biodiversity)

In a nutshell: why we need to protect lands on the west side of Sandy Lake

We already have ~1000 acres protected, most of it on the east side of Sandy Lake. So why did Walter Regan ask at the Dec 6, 2018 presentation:  “Why do we need those lands on the west side?” ( I am pretty sure Walter knew the answer.)

The following slides/maps explain it all “in a nutshell”:

Sandy Lake frozen over on Dec 13, 2018 & salt signal increases in streams entering lake via Johnson’s Brook

Revised Dec 17, 2018

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

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

“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.
