As transportation networks expand and urban areas grow, noise from sources such as vehicle engines is spreading into remote places. Human-caused noise has consequences for wildlife, entire ecosystems and people. It reduces the ability to hear natural sounds, which can mean the difference between life and death for many animals, and degrade the calming effect that we feel when we spend time in wild places.

Protected areas in the United States, such as national parks and wildlife refuges, provide places for respite and recreation, and are essential for natural resource conservation. To understand how noise may be affecting these places, we need to measure all sounds and determine what fraction come from human activities.

In a recent study, our team used millions of hours of acoustic recordings and sophisticated models to measure human-caused noise in protected areas. We found that noise pollution doubled sound energy in many U.S. protected areas, and that noise was encroaching into the furthest reaches of remote areas.

Our approach can help protected area managers enhance recreation opportunities for visitors to enjoy natural sounds and protect sensitive species. These acoustic resources are important for our physical and emotional well-being, and are beautiful. Like outstanding scenery, pristine soundscapes where people can escape the clamor of everyday life deserve protection.

The Biodiversity Monitoring Institute Reports on Alberta

The Alberta Biodiversity Monitoring Institute (ABMI) has released a series of reports that can be used to observe changes in land use and environmental variables.

See these web pages:

Land Cover

Human Footprint Map

Species

Some  of the map products will be useful for monitoring of the Sylvan Lake watershed, however the resolution is too low to monitor changes at the community or individual property scale.

News from the Alberta Recreational Lakes Forum 2017

Alberta Environment and Parks organized this year’s forum at Lake Isle west of Edmonton.

Several forum documents and presentations are filed in this online SLWSS folder.

The SLWSS did not attend this year’s forum as the need for input from community stewardship groups has declined. We did provide this report on our 2016 activities and projects:

SLWSS REPORT FOR THE ALBERTA RECREATIONAL LAKES (ARL) FORUM 2017

State of the Watershed 2016

Our comprehensive report “The Sylvan Lake Watershed-Second Edition” documented changes in the key indicators that affect the state of the watershed. Data on Environmental, Social and Economic Cumulative Effects variables were compiled for time periods of one or more decades and presented a picture of a relatively stable environment.

Water Quality Monitoring 2016

Preliminary analytical data indicate that in a year with little spring runoff the nitrogen and phosphorus nutrient concentrations have been lower than the long-term average. The lake water clarity remained very high with Secchi disk depth measurements typically greater than 5 metres. Photo albums of the lake sampling expeditions were posted on our SLWSS News blog site.

Nature Alberta’s Living by Water Program

The Society has promoted the Nature Alberta Living by Water program for several years and enabled more than 80 property owners to benefit from Home Assessments. Response to L by W has declined and we awarded a SLWSS yard sign to just a single property owner in 2016.

Government Affairs in 2016

The Society presented a statement on the potential impact of the West Area structure plan at a public hearing of the Town of Sylvan Lake with regard to transport of silt from construction sites through Marina Bay into Sylvan Lake in Golf Course Creek runoff. We recorded several cases of increased turbidity in stormwater runoff.

Groundwater Research

We assisted a University of Calgary geophysics survey team led by Profs. Lauer and Bentley to collect groundwater aquifer data at the west end of Sylvan Lake in October.

Quiet Enjoyment Initiative

The QEI subcommittee chaired by Kent Lyle continued its efforts to have local municipal bylaws adopted to control the sources of noise on the lake. An education and boat launch site signage project was developed at the request of the SLMC. Subsequent support by the municipal members of the SLMC was mixed and disappointing to the hard-working sub-committee. The QEI message resonated with and received considerable major and local media interest in its efforts to promote respect for others. An expanded QEI subcommittee report is posted here.

Community Outreach

Our ceramic tile for the new lighthouse is mounted on the structure with inscription: “Sylvan Lake Watershed Stewardship Society: Protecting the lake’s natural assets and values through vigilance and science”.

 

 

 

Juno Beach Comes to Sylvan Lake

The shoreline of Sylvan Lake is changing as McMansions replace those old time family summer cottages.

Architectural, environmental and aesthetic standards seem to be flexible. Living by Water principles that help property owners manage water balance and preserve the riparian zone with recommended low impact development and landscaping standards in some cases have apparently been eaten by the family dog.

One Birchcliff SV property owner has prepared for an invasion by sea as this section of re-contoured escarpment and shoreline now resembles Juno Beach in 1944:

Birchcliff vs Juno Beach

Shoreline impairment surveys document the degradation of the naturally protective riparian zone around the perimeter of the lake.

Sylvan Lake Boat Launch Access

The Sylvan Lake News has reported on the status of a Town of Sylvan Lake initiative to improve the convenience and reduce the cost of boat launch access at the private Sylvan Lake Marina:

Affordable access to lake remains an ongoing issue

From the stewardship perspective, lake protection is typically is not a top priority for power boaters. Demonstration of a concern for shoreline erosion, impacts on aquatic habitats, and the level of noise pollution is not a prerequisite for acquisition of a Boaters Card.

The Society has contributed an analysis of the inter-municipal lake access report to the Town of Sylvan Lake.
