Natural Resources Wales says a large number of Larch trees will have to be felled in Cwmcarn Forest.
It says an aerial survey in May this year revealed widespread infection by Ramorum disease. More than three quarters of the trees in Cwmcarn Forest are Larch.
So a large amount of the forest will need to be felled over the next few years to remove dead or dying trees that have been infected with the fungus-like pathogen Phytophthora ramorum, which causes the disease.
NRW says the felling is needed because infected trees produce airborne spores that can spread the disease, which is not harmful to humans or animals, to other areas and other tree species.
Caerphilly County Borough Council is accusing the governing body of Cwmcarn High School of taking too long to make a decision on when work to remove asbestos from the site should begin.
In April, the council announced that the school would reopen, with pupils taught in temporary accommodation on the site while the work is carried out.
The school was closed in October 2012 after the discovery of the material within the school buildings.

I would like to assure the school community that we are ready to move quickly as soon as a decision is made, but we are becoming increasingly frustrated by the school’s lack of progress and it now seems we must wait until next week for a decision to be made.
Time is fast running out and I would urge the school leadership to take decisive action before we miss our window of opportunity to get the work done in time,” he added.
A decision is expected later over the future of Cwmcarn High School. Caerphilly County Borough council will hold a special meeting to consider whether the school can be kept open.
The school was temporarily closed in October 2012 after a report found high levels of asbestos there.
A recent survey recommended removing the asbestos and further work to make the school safe. This would cost around £1million.
The school and the governing body say they want to proceed with the work to keep the school open, but that the Councillors will consider a range of other options later today.

She basically came home from school and said 'Mam I've been sat in a classroom with a hole in the wall and an asbestos sticker on it'. I mean this was back just before they broke up for the summer. And then the testing was done. What will happen next year? Will the school reopen or will they pull it down? We just don't know.
An investigation published yesterday into Cwmcarn High School says asbestos in the roof may have been blown by the heating system and airborne fibres were 10 times higher than the accepted levels. Today special health clinics are being held for concerned parents and pupils.
