Bluebells flowering much earlier

Blackpool Citizen: The Woodland Trust said warmer weather has led to bluebells flowering earlier than last year The Woodland Trust said warmer weather has led to bluebells flowering earlier than last year

Bluebells are flowering much earlier than in last year's cold spring, with peak displays expected in time for Easter, the Woodland Trust said.

The charity said nearly 200 records of native bluebells had been submitted to the Nature's Calendar website, which asks the public to submit sightings of natural events which mark the changing seasons.

This time last year, just 43 records had been submitted, as the UK struggled to shake off cold weather.

The trust is expecting a much earlier average first flowering date for bluebells than in 2013, when the average date across the UK was May 5. The earliest average first flowering date on record was April 4, in 2012.

Long term records show that the flowering dates for English bluebells have got five days earlier in the last 50 years, the Woodland Trust said.

Other spring species are flowering up to 12 days earlier over the last 25 years, as a result of climate change, according to the charity.

The Woodland Trust is calling for better protection of ancient woodland, one of the native bluebell's key habitats, to give the plant the best chance of survival in the face of increasing threats from climate change, development and invasive species.

Woodland Trust director of conservation Austin Brady said: "Climate change is not only affecting flowering dates but is also a factor in the number of pests and diseases in the UK quadrupling since the year 2000.

"Combined with Government's clear misapprehension that ancient woodland is protected from development, the Woodland Trust is deeply concerned about the future of English bluebells and many other native species.

"Increased protection for all ancient woodland is vital, and linking them with newly planted woodland and hedges will allow wildlife safer passage through the countryside.

"This will help to make our countryside more resilient, and offer more scope for adaptation to the impact of climate change too."

Do keep up - Easter 2014 is 20 days later than 2013, so it's little to do with climate change.....lots to do with changing dates on a calender !!

4 mentions of 'Climate change' ????
Climate change has only been happening for the last 4billion yrs, so to put the “carbon” scare into perspective: CO2 has increased from about 3 parts in 10,000, to only 4 parts in 10,000 — in 150 years.

Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the “CO2 fertilization” effect—the enhancement of photosynthesis due to rising CO2 levels—is yet to be established. The direct CO2 effect on vegetation should be most clearly expressed in warm, arid environments where water is the dominant limit to vegetation growth. Using gas exchange theory, we predict that the 14% increase in atmospheric CO2 (1982–2010) led to a 5 to 10% increase in green foliage cover in warm, arid environments. Satellite observations, analyzed to remove the effect of variations in precipitation, show that cover across these environments has increased by 11%. See-

2013 was the same temperature as 1666 !!!....with a few fluctuations in-between.

Despite all the hype we are still 2°C colder than 2,000yrs ago
