A row is brewing over plans for a £12 million hydro-electric scheme near Betws y Coed in Snowdonia.
The scheme would involve abstracting water from the river above Penmachno bridge and diverting it through 1,000 metres of pipeline around the Fairy Glen before returning it to the river near the junction with the River Lledr.
Developers RWE Innogy say it would provide energy for around 2,700 homes.
But Coed Cadw, the Woodland Trust, says nearby woodland would be affected.
"Ancient woods are our richest, most important sites for a vast range of insects, birds, animals, flowers and trees and are home to more threatened species than any other UK habitat.
"We simply cannot afford to lose them, and fencing off areas for natural regeneration can never compensate for their loss."
Residents of Newtown will have their say on a new proposed bypass around the Mid Wales town.
The £58 million bypass is due to be completed by 2017 if it gets the go ahead, although it has faced some criticism based on the initial outlines of the route.
"We are now on the cusp of what could be the largest investment in the area for a generation, with a £58million pound bypass along the A483 at Newtown, £20million of commercial development in Newtown and the investment in a fibre-optic broadband network providing high speed broadband access throughout the area"
A planning inspector will take 12 weeks to prepare a report on the new bypass based on suggestions from the public over a 3 week period.
The public enquiry is due to start at 10am at the Elephant and Castle Hotel in Newtown.
Pembrokeshire based voluntary group Neptune’s Army of Rubbish Cleaners (NARC) is celebrating its 10th anniversary this dive season.
Founded in 2005 by local diver Dave Kennard, the army of volunteers has carried out hundreds of dives to help protect the coast of Pembrokeshire.
As well as the more common finds such as plastic bags, shopping trolleys, bikes, cans, tyres, lost angling gear, the group has stumbled on some more surprising discoveries including satellite dishes, a Mitsubishi van and even a kitchen sink.
It’s amazing to have been going for 10 years. What started out as a mission to tackle marine litter that is often out of sight, out of mind, has grown into an established group with regular clean ups, hard working volunteers and strong partnerships with local schools, the community, fishermen and our funders. We are not trying to just protect our marine environment by collecting litter but also educate everyone to consider the conservation of our beautiful coastline.

Did you catch the Northern Lights over Wales last night?
Many of you did see The Aurora Borealis and have been sending in your photos.
If you missed it then watch this film captured over three hours at Cemaes Bay, Anglesey by@rayvon0 and speeded up.
And, weather permitting, the forecast for Friday suggests it may be another good night for catching the lights.
The tidal energy "fence" across the Bristol Channel would cost around £143m and could be ready by 2020.Read the full story ›
Around three days ago the Sun launched a CME (Coronal Mass Ejection), containing millions of tons of charged particles, more or less straight at the Earth.
It is hitting the Earth's magnetic field.
The charged particles are chanelled down the field's lines and into the Earth's atmosphere.
Here they interact with the atmosphere's atoms and produce light.
The colour depends on the atoms they hit.
