Wind turbines and birds and bats

Cross border factors are also present. Political decisions are being made in Ontario without considering the factual information about these issues. The MSM is compliant with what is taking place with some exceptions. The same is true in the U. Two factors that skew their statistics are the radius that they use to do the count and the timing of the count.

They only collect carcasses in a 50m radius. BSC says that the numbers would be On top of this they only collect some months of the year. Um, that might really skew the numbers. Oh and they only collected carcasses under 18 of the 38 turbines weekly, the rest on a monthly basis for 6 months. So basically they picked which turbines they wanted to collect under like not the one near the bat roost, or not the ones near the eagle nest… you get the picture.

These number in the BSC report are bad enough, but they are only the tip of the iceberg. In Huron County, there was a site where hundreds of brown bats returned to each year.

The site had to be renovated so they diligently took the care to build appropriate housing on the same site for them and they had it ready on time, but no brown bats returned. Could this be why? There is a part of this study that specifically tracks the percentage of carcasses that are removed by scavengers at each site.

We are fighting turbines. Has anyone found any recent data to show how many little brown myotis have been killed in the past year by turbines? And in the three previous elections, the percentage was only slightly smaller. So, tell me something, all you folks who voted consistently for all things green — like solar panels and wind turbines……any regrets? Sitting in England here reading this in horror.

These companies are criminal and all the idiot greenies who support them need to take a good look at themselves. Good article which I will share. Your email address will not be published.

Average of bats killed by just one Ontario wind turbine: Amount supposedly allowed by MNRF per wind turbine: Ya the snappy title might be good like Murder not allowed serial killers excluded Wind industry is the serial killers that just keep on going, perhaps one day an light may come on when billions of birds and bats are killed and people may ask why was this allowed to go on for so long.

Calvin Luther Martin, PhD. Diligent maintenance should be performed on wind turbines and other equipment so as to reduce risks to birds. For example, keeping nacelle drainage holes properly capped will prevent birds from entering the turbines to roost or nest. Wind farm operation should be carried out in the most biodiversity-friendly manner feasible. With respect to migratory birds in particular, this means avoiding green landscaping around wind farm offices, transporting food wastes or other organic refuse for proper disposal away from the wind farm, and otherwise avoiding the creation of landscape features that could attract more birds to the wind farm area.

Construction operations and the building of access roads can increase the public access and use of previously isolated areas, which may have an impact on resident species present in an area. Any fencing or ancillary features should not hinder animal migrations, where vulnerable species such as grouse or bustard species are present. Flight diverters should be used to make fences clearly visible. Post-construction monitoring during wind farm operation includes at least two to three years of systematic searching for dead bird and bat carcasses underneath wind turbines and masts.

This monitoring should follow a scientifically valid methodology that takes into account searcher efficiency some carcasses are overlooked and scavenger removal in estimating the total number of bird or bat fatalities, as well as unusual climatic conditions.

The results of monitoring should be used for annual evaluations of whether different or additional mitigation measures are needed, and after the initial period, whether monitoring should continue for additional years or seasons. Post construction monitoring should also include bird observations that were carried out pre-construction.

Wind farm operators and regulators should endeavor to disclose publicly the biodiversity data obtained from monitoring, so that this information can guide future wind power development and help to advance scientific knowledge. Wherever possible, government or nongovernmental organizations should develop formats in which data can be organized for future use. Short-term shutdowns may be the result of recommendations made during post-construction evaluations.

Prior to wind farm commissioning, a capability should be established—using human spotters, radar, or both—to implement short-term shut downs STS on demand, such as when a flock of migratory birds is noted approaching the turbines.

Scientifically credible, operationally feasible, and cost-effective criteria and procedures for STS must be developed before wind farm commissioning and then refined as needed in response to the findings from post-construction monitoring.

Capacity factor reduction must be anticipated. In the event that post-construction monitoring finds significant bat mortality at wind turbines, increasing the night-time turbine cut-in speed to 6. Enlisting stakeholder support can help fill gaps in data collection and analysis. Local universities, as well as national and international nongovernmental organizations, can provide both data and expertise for developers, lenders, and regulators.

Uniform technical guidelines for addressing biodiversity issues in wind power projects could support national and regional standardization and cooperation by specifying criteria and good practices for technically challenging mitigation measures, such as short-term shut downs and modified cut-in speeds, and recommended methods for pre- and post-construction monitoring, including standard protocols for data collection, presentation, and sharing.

To understand better the impacts of wind power on birds and bats and how to minimize them, the CIF has been bringing together representatives from CIF pilot countries governments, civil society, private sector, multilateral development banks MDB , and other partners in a series of roundtable discussions and learning workshops to share experiences and innovations.

Our growing community is sharing website, reports, and other resources to create connections and advance understanding and action. Wind turbines and transmission lines can displace bird and bat populations and disrupt breeding and feeding.

Although not an exhaustive list, contributors suggest guidance on: Strategic Environmental Assessments SEA , which are assessment processes that go beyond project-level and aim to integrate environmental and social considerations into strategic decision-making, can help balance opportunities and constraints for wind energy development and identify favored and non-favored areas for development by: Identifying regional topographic and other effects that can concentrate migrating birds that are vulnerable to wind projects into broad fronts or bottlenecks, or that concentrate feeding, roosting, or breeding birds.

Identifying areas where barrier effects may occur, causing birds to divert around turbines and wind farms and thus expend more energy to reach breeding, wintering, feeding or other destinations. The barrier effect can also imply that habitats used by birds or other fauna adjacent to wind developments may also suffer an impact, meaning the effect of the development is greater than the area itself.

Buffer zones merit consideration as do assessment of contiguous habitats. Considering other existing or planned land uses in the region.

Addressing cumulative impacts of multiple wind energy developments upon same species and populations. Conservation status of the land e. Migratory bird survey to cover the two migration seasons. Within key areas of global flyways, the use of radar to aid assessment of migration movements is ideal. Breeding bird surveys to assess the potential footprint and buffer zone impact of a development on resident species and baseline conditions present in the area.

Vulnerable and protected species specific surveys that need individual assessment e. Wintering ornithological surveys may also be required, which could include non-breeding surveys and those for resident and over wintering migrants. Electrified wires at the same height are at least 2. Insulators and similar electrified devices either point down from the cross-pole where a bird might perch or are otherwise outside the normal stretching reach of a perched bird.

Measures to minimize fatal bird collisions with the guy wires of masts wind measurement towers include: Placing bird diverters or flappers on guy wires to help prevent collisions. Promptly removing any masts that are no longer needed or non-functioning.

Measures to minimize this risk include: Using night lights on nacelle tops required for aviation safety, but with the minimum number of lights not on every turbine to show the wind farm dimensions consistent with aviation regulatory requirements.

Choosing white strobe lights which minimize bird attraction , rather than solid or slowly pulsating red or white lights.
