The waves are obviously spreading knotweed around the coast. Obvious really when you think about it.

Here is a beaver kit on the river Ericht outside Blairgowrie getting stuck in to the lower leaves of Japanese knotweed. Which of these causes the most problems on rivers?
Pity we did'nt get as much excitement about eradicating JapKnot and other invasives on the Tay as we did in recent years about the beavers.
Well done that Scottish- born beaver...!

Dressing up in full PPE was no fun on a hot day, and after cutting a few flowerheads, we decided to spray smaller plants around the edge of the colony, and come back next spring to deal with plants when they are a more manageable size. Caution is the better part of valour.

Highlights how devastating a predator the mink can be wiping out a kingfisher nest in a matter of minutes. This is the case for many ground nesting birds and water voles.

American skunk cabbage was introduced to Britain in 1901, and was first recorded in the wild in 1947. Skunk cabbage is a popular plant in water-gardens, and has been actively promoted by the gardening press. In 1993 Lysichiton americanus received an “Award of Garden Merit” from the Royal Horticultural Society (RHS) Floral Committee.
More recently, greater attention has been drawn to its invasive nature. In 2010, the Recording Invasive Species Counts (RISC) project asked the public to submit records of Lysichiton americanus. The RHS website now provides an online leaflet on invasive plants in which it recommends that gardeners should “Avoid using plants known to be invasive, especially in the case of non-native aquatic species”.
Nevertheless, Skunk cabbage is still praised as a garden plant. The online BBC Plant Finder describes it as “an asset in any bog garden”, and makes no mention of its ability to spread into the wild. Skunk cabbage is still widely available from plant nurseries.Although it is less invasive than some non-native plants, it is dispersed readily by flowing water. A watchful eye is best kept on any populations which have escaped into the wild. Fortunately, it can be controlled relatively easily.
Note the mass of young plants close to the parents, suggesting that the seeds are not often carried far, unless by flowing water. In the Pacific regions of North America where Skunk cabbage is native, the seeds appear to be dispersed by animals.
However no bears were seen in this wood on the Morvern peninsula.

"An outbreak of the Asian longhorn beetle (ALB), an exotic beetle pest which could have severe consequences for British trees, has been found in Kent the Food and Environment Research Agency confirmed today. This is the first time an outbreak of this pest has been found in the UK and it is being treated extremely seriously. Fera and the Forestry Commission are taking urgent steps to try to eradicate the outbreak before it has the chance to spread further afield."
"The Killer Shrimp is just one of the non-native crustaceans that arrived in Great Britain after invading into Europe. To help raise awareness of this and other species and support detection, Defra have funded the Freshwater Biological Association to produce an identification guide to existing and potential new invaders. "
Giant hogweed is best tackled early in the season, before it grows too tall and scary!
Roots can be severed with a sharp spade, unless the soil is very stony.

Here is a link to a very interesting article highlighting reasearch that has been carried out by the University of Leeds on the affect of the invasive American Signal Crayfish on native White Clawed Crayfish in England and the freshwater ecosystems as a whole: http://www.sciencedaily.com/releases/2012/03/120315095519.htm

Not sure if this has been posted before but it certainly has some interesting figures which are worth quoting if you are ever having to justify INNS control work.

These cliffs on the west coast of Mull support a rare moth and a well-established population of the bush Cotoneaster microphyllus, a native of the Himalayas. Gardeners are encouraged to plant Cotoneaster for its berries, which are attractive to birds. Unfortunately, the birds then go and plant it where it is less welcome.

In 1974, a bird new to science was discovered in Patagonia. Only a few decades later, it is now considered to be Endangered. Its numbers have fallen for various reasons, but the introduction of non-native trout has contributed to the decline. Introduced American mink have also been spreading in western Patagonia. When researchers visited one of their breeding sites in March this year, they found mink had devastated the colony. Over 30 breeding adults were killed, and over 40 eggs abandoned.

This was demonstrated last week during a workshop on rhododendron control at Kinloch Hourn. Thanks to all the 'rhoddy experts' who contributed, and the Estate, who provided material to practice on.

The Scottish Mink Initiative aims to create a 20,000 sq km safe haven for native wildlife in rural Tayside, Aberdeenshire, Moray, the Cairngorms and the Highlands. The initiative aims to protect native wildlife, such as water voles, ground nesting birds and economically important populations of salmon and game birds.
There are five full time members of staff - four locally based Mink Control Officers who recruit and coordinate volunteer effort and a Coordinator who oversees the day to day running of the project:
Project Coordinator: Hollie Walker 07825 183 037 firstname.lastname@example.org
Aberdeenshire: Sarah Atkinson 07825 180 319 email@example.com
