T<\/strong>he alien invasive spruce bark beetle\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 continues to crop up in the UK with the latest discovery in Scotland and a first for that country. This is certainly the scariest identification so far given that the bulk of commercial forestry in Scotland is based on Sitka spruce. This latest finding of\u00a0\u00a0 Ips<\/em>\u00a0\u00a0 typographus<\/em>\u00a0\u00a0 in Scotland was of a single beetle picked up in an improved insect pheromone trap and deployed as part of Scottish Forestry\u2019s new surveillance programme. However, to put the finding into context Scottish Forestry says it is just a single\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 beetle found amongst 6,500 other insects and covering 40 different species.<\/p>\n

James Knott, head of tree health at Scottish Forestry said: \u201cAlthough this is the first time we have found\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 in Scotland, we currently believe it is a one-off that hitch-hiked here.\u201d Now I take that comment to suggest the beetle came in on a crate or a suitcase and not as a pest on its natural host tree material which in this case is spruce timber and wood with bark and most likely Norway spruce.<\/p>\n

Indeed, Scottish Forestry says the beetle found in woodland in Fife is believed to have arrived on the back of goods being shipped into Scotland via the port of Grangemouth. As an Englishman my knowledge of Scotland, both in geography and trading patterns is notoriously sketchy so I checked both the relevant geography and the nature of trade going through Grangemouth Port and this is what I found out:<\/p>\n

Grangemouth is on the Firth of Forth within the county of Stirling and Falkirk, historically in the County of Stirlingshire but now falling within the unitary authority of Falkirk. And low and behold Grangemouth is just two miles south-west of the boundary with Fife.<\/p>\n

So what about trade aspects? Grangemouth is one of\u00a0\u00a0 the Forth Ports and Scotland’s largest individual port, handling 9 million tonnes of cargo each year through liquid, specialist container and general cargo terminals. Imported goods include food, drink, machinery, steel products, paper and timber, the latter being the\u00a0\u00a0 import of interest here.<\/p>\n

Forth Ports has a dedicated forest products terminal at Grangemouth and there will apparently soon be a massive biomass burning plant operating at Grangemouth. When planning permission was granted back in 2013 for the biomass burning plant objections were raised by Green MSP (Member of the Scottish Parliament) Alison Johnstone who said the plant would burn up to 1.5 million tonnes of imported wood every year. Commissioning of the plant was scheduled for late 2023.<\/p>\n

No mention of where the wood is likely to come from (or indeed whether wood is arriving already in anticipation)\u00a0\u00a0 and the sort of tree species involved, but conifers including spruce are likely to be involved and sourced from continental Europe where\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 has run riot for centuries if not millennia on Norway spruce. And clearly the easiest and cheapest source of foreign wood earmarked for biomass burning\u00a0\u00a0 in the UK including Scotland.<\/p>\n

No mention of what port the wood for biomass burning was likely to come in through but for proximity and economy Grangemouth would appear to be the obvious choice.<\/p>\n

I use the term wood advisedly because material for biomass burning is likely to be low grade wood and logically more likely to be suffering from pest infestation and perhaps less likely to undergo as thorough inspection as high grade timber for cutting and construction. If the\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 beetle did indeed come in through Grangemouth as Scottish Forestry implies, and specifically within imported bark-covered spruce timber or wood, then I would not choose the term \u2018hitch-hiked\u2019 to describe the pest\u2019s ride into Scotland.<\/p>\n

Scotland is lucky if this is a \u2018one off\u2019 beetle which Scottish Forestry says it is. And a lot more fortunate than England where established breeding populations of\u00a0\u00a0 Ips<\/em>\u00a0<\/em>\u00a0 typographus<\/em>\u00a0\u00a0 have been found across Southern England since 2018. The first was in Kent with subsequent findings in East and West Sussex and then Surrey, with at least 23 outbreaks reported by August 2023, apparently all on Norway spruce. UK government says: \u201cOutbreaks have resulted from natural dispersal (blow over) of\u00a0\u00a0 Ips typographus<\/em>\u00a0\u00a0 adult beetles from the continent. They say there is no evidence of onward dispersal from any outbreak site in England.\u201d The type of evidence on which this assumption is based has not been specified.<\/p>\n
