Scottish rainforest silent killer' rooted out by scientists
Yet, their survival has been threatened by thickets of rhododendron, first introduced to the UK as ornamental plants two centuries ago.
However, progress is being made. Ahead of World Rainforest Day on June 22, Forest and Land Scotland (FLS) have announced a new milestone in their restoration efforts over the last year.
FLS teams restored 1226 hectares in 2024/25, up from 930ha last year. Work included removing invasive rhododendrons, returning native species to the forest, and ensuring deer populations are effectively managed.

One 'practical and targeted' solution involves injecting each the stem of each plant with a small dose of herbicide.
FLS Native Woodland Ecologist Richard Thompson praised his team's work in combating the rhododendron scourge.
Thompson said: 'Following on from the success achieved by the National Trust at some of its sites, FLS is starting to use stem injection at large landscape scale. Results have been encouraging and we are hoping to roll out its use more widely across other FLS managed rainforests.
'FLS manages a substantial proportion of Scotland's rainforest, and with around 8000 hectares of priority rainforest rhododendron areas on land managed by FLS it is imperative that effective and efficient control measures at landscape scale can be refined and deployed.
'However, to truly control the spread of Rhododendron, it needs a strategic, collective and collaborative effort from all landowners and managers including estate and residential gardens.'

In 2020 the National Trust for Scotland launched Project Wipeout, targeted at invasive species like rhododendron.
According to the Trust: 'Cross breeding with frost-hardy rhododendron species from north east America has produced hybrid vigour and helped the plants adapt to colder temperatures.
'Together with its fertility and tolerance of shade, the plant has been able to thrive in our climate and out-compete native flora.
'Almost half of the core areas of Scotland's rainforests are being choked with R. ponticum.'
Project Wipeout has been rolled out across Scotland over the last five years.

Urgent repairs under way at 15th Century Oxburgh Hall in Norfolk
An urgent conservation project is under way to preserve a manor house built more than 500 years levels in the moat at Oxburgh Hall, near Swaffham in Norfolk, became unusually low due to leaks last year and then a sinkhole appeared on a lawn.A watertight enclosure called a cofferdam has been installed to allow contractors to repair the moat as part of work costing £196, Baldwin from the National Trust said it was a "delicate balancing act" to keep water levels high enough to protect the building's walls without flooding the gardens. "If the water drops too low, the brickwork is exposed, which has an impact on the structural integrity of the hall itself," she said. Workers are expected to remain at the site until the end of June and will also repair the sluice and moat is fed via an underground channel from the River Gadder, with culverts allowing water in and out. The sluice gate controls the amount of water draining out of the moat and back to the Gadder. The Oxburgh Estate is owned by the National Trust but has been the family home of the Bedingfelds for more than 500 years, and they still live in private apartments at the hall.

Middlesbrough's Ormesby Hall to fell trees due to ash dieback disease
Work will begin to fell a hundred trees suffering from ash dieback disease on a historic estate during nesting National Trust, which manages Ormesby Hall in Middlesbrough, was granted planning permission for the work to begin in January, but it was pushed back for an ecology assessment to be carried trust said it was satisfied with measures in place to protect wildlife and described how the trees potentially posed a risk to the public should they become too weak and disease is a fungus which infects ash trees, attacking leaves and branches, causing lesions, and eventually leading to their death. Mark Bradley, countryside manager with the National Trust, told the Local Democracy Reporting Service (LDRS) that "it was not ideal" to be carrying out the work during nesting said there was a benefit to carrying the work out during the drier season and that exclusion zones had been set up around nesting sites. "To manage risks, before we began the tree work, we assessed the site and considered what needed doing against the potential impacts on wildlife and the environment."We also do what we reasonably can to avoid disturbing or damaging birds' nests," he of the trees affected on the estate had been planted in Pennyman's Woods in the some older trees running along the nearby roadside, were probably more than 200 years old but would also have to come Bradley said: "As Europe's largest conservation charity, we take all our work of this nature extremely seriously and operate to what we believe are the highest standards."Our risk management of nest sites is above and beyond the norm."
