Gower's commons occupy a large percentage of the peninsula's land surface. Their open expanses are often criss-crossed with well sign-posted public footpaths, allowing visitors access to some truly diverse wildlife. Bracken (Pteridium aquilinium) often dominates the scene, along with indigenous species of heather. Reaching its northern Europe limit, Bristle-bent Agrostis curtisii can also be found on Gower commons as can the rare soft-leaved sedge.
The Marsh Fritillary butterfly is one of the more beautiful insects along these landscapes whilst Peregrine Falcon, Merlin, Sparrowhawk, Kestrel and Buzzard frequent the skies here in search of rabbit, stoat and mice. Evening visits may reward the visitor with rarer glimpses of Barn Owl and Short-eared Owl.
The largest commons on Gower are Fairwood Common and Cefn Bryn with the latter being the more popular as it also holds both Broad Pool and the ancient historic monument, Arthur's Stone.
Gower has some of the very best woodland habitats. Bishopston Valley is densely populated with a long meandering wood that stretches down to the very quiet Pwlldu Bay. Fox and badger are present here in good number. Amongst its bird life, Crossbill, Great Spotted Woodpecker, Green Woodpecker, Coal Tit, Firecrest and Chiffchaff can be spotted here as they can amongst most of the indigenous woodland on the peninsula. Betty Church is a smaller wood decorating the north Gower coastline between the villages of Llanmadoc and Cheriton. Most woodland plant species can be found growing here. Another woodland site worth visiting is the very sedate walk offered at Parc-le-Breos in Parkmill (a good chance of spotting a Nuthatch here).
Gower's Carboniferous Limestone Cliffs are amongst the most spectacular in the whole of the UK, particular between Port Eynon and Rhossili where the coastline become progressively more rugged and picturesque. Sheltered beneath these cliffs, or occupying the breaks between them, are an array of beaches ranging from small pebbly coves like Limeslade to huge expanses of Sandy Bay like Oxwich and Whiteford.
Oystercatcher, Bar-tailed Godwit, Sanderling, Ringed Plover, Dunlin, Redshank, Ruddy Turnstone, Cormorant, Mediterranean Gull, Shag, Guillemot, Razorbill, Kittiwake, Fulmar, Puffin and Gannet number amongst the birds likely to be encountered around Gower's southern coastline. There are also several R.I.B. operators, such as Coastal Rib Tours, offering guided boat trips along Gower's coast which allow for closer wildlife encounters with the aforementioned birds and also the Atlantic Grey Seal and Harbour Porpoise. Hermit Crabs can often be seen by the horde along the tide line at Rhossili and Llangennith Bays at sunset and Three Cliffs Bay often has washed ashore jelly fish of quite substantial size for the curious to gaze at. Caswell and Oxwich Bays are probaly the best for those wanting to spot starfish while Rhossili (on the causeway to Worm's Head) is the perfect spot for rockpooling.
There are numerous ponds scattered across the Gower Peninsula, the largest being Broad Pool on Cefn Bryn. Water Lillies are perhaps the most notable wildlife located here, as well as dragon flies and water fowl. A smaller pond, located along the Marsh Road near the village of Crofty sports a rather lively community of three-spined stickleback as well as the common frog and toad.
Gower's numerous rivers are all narrow and winding in character and host a good variety of indiginous fish life. Young plaice and eel are easily located under the small bridges near the children's park at Crofty while trout can be spotted along the same river further inland. Bull Heads, minnows and larger eel are probably best spotted in the River Ilston. This particular river also plays home to perhaps Gower's most beautiful residents - Kingfishers.
The entire northern coastline of Gower is dominated by the expanse of the Burry Estuary. Here can be found a variety of birdlife including: Oystercatcher, Curlew, Wigeon, Brent Geese, Pintail, Little Egret, Heron, Common Eider, Great Crested Grebe, Redshank, Black-tailed Godwit, Grey Plover, Ringed Plover and Dunlin.
Ponies, sheep and cattle graze the grasses which cover the inland areas of the marsh, and foxes have been seen meandering the maze of river channels which criss-cross the plain. Amongst the more open sediment areas of the marsh, various species of crab can be found. Further out along the marsh, large cockle beds are visited daily by local pickers. Several cockle-processing buildings can also be seen around the inland fringe of the Estuary near the village of Crofty.
