Mae'r darn 11 milltir o adran 5 a 6 yr A465 yn rhedeg drwy dirwedd amrywiol. Mae'n cynnwys:


* yr ardaloedd trefol adeiledig o amgylch Merthyr Tudful
* trefi a phentrefi
* safleoedd ôl\-ddiwydiannol
* tir fferm
* coedwigoedd,
* cronfeydd dŵr.


Ceir hefyd amrywiaeth eang o dir sy'n nodweddu Blaenau'r Cymoedd. Dyma sy’n ffurfio bioamrywiaeth yr ardal.


Mae cefnogi bioamrywiaeth ar hyd llwybr adran 5 a 6 yn bwysig. Mae'r ffordd wedi'i dylunio mewn modd sy’n ceisio cynnal tirwedd naturiol a nodweddion diwylliannol yr ardal.


Cynhaliwyd arolygon amgylcheddol cyn i'r gwaith adeiladu ddechrau.


Mae'n brosiect mawr, a hyd yn hyn rydym wedi cyflawni:


* 100 o arolygiadau
* 313 o arsylwadau amgylcheddol
* 4,000 awr o oruchwyliaeth ecolegol


Mae hyn oll wedi ein helpu i ddarganfod pa fath o fywyd gwyllt sy'n byw yn yr ardal. Buom hefyd yn edrych ar y pridd a'r planhigion i weld pa fath o gynefinoedd sy'n gallu cefnogi'r bywyd gwyllt.


### **Yr hyn a ganfuwyd gennym**


Dangosodd yr arolygon fod sawl rhywogaeth yn byw ar hyd y llwybr. Roedd y rhain yn cynnwys:


* ystlumod
* pathewod
* Madfallod Cribog Mawr
* cornchwiglod
* Glöynnod Byw Britheg y Gors

### **Sut y byddwn yn gwarchod y bywyd gwyllt**


Er mwyn sicrhau bod gan y rhywogaethau hyn y lle sydd ei angen arnynt i ffynnu, rydym yn:


* creu cynefinoedd newydd i ffwrdd o'r ffordd, gan gynnwys rhostir a choetir
* symud tamaid y cythraul, planhigyn sy'n cefnogi Glöynnod Byw Britheg y Gors
* gosod tai ystlumod
* creu pwll Madfall Ddŵr Gribog
* tynnu, storio ac ailddefnyddio uwchbridd
* prynu tir ar gyfer safleoedd bridio newydd, wedi'u rheoli, ar gyfer cornchwiglod
* symud gweoedd larfal Britheg y Gors i ardaloedd diogel, gan gynnwys tir fferm
* gosod 421 o bydewau maglu mewn ardaloedd sydd wedi'u ffensio i symud dros 1,000 o amffibiaid neu ymlusgiaid yn ddiogel o'r gwaith. Mae'r rhain yn cynnwys:
	+ 57 o Fadfallod Ddŵr Gribog Fawr
	+ 123 o Fadfallod Dŵr Balfog
	+ 61 o Frogâod Cyffredin
	+ 496 o Lyffantod Cyffredin
	+ 65 o Fadfallod Cyffredin
* symud pathewod i gynefin newydd mewn 6\.33 hectar o dir
* tyfu 8,000 o blanhigion sy'n cefnogi Glöynnod Byw Britheg y Gors
* cael gwared ar blanhigion sy'n dinistrio strwythurau ac yn ei gwneud yn anoddach i blanhigion defnyddiol dyfu
* plannu dros 55,000 o goed a llwyni newydd i gymryd lle'r rhai a dynnwyd gennym i adeiladu'r ffordd


Mae'r gwaith rheoledig hwn yn cael ei fonitro gan:


* Llywodraeth Cymru
* Cyfoeth Naturiol Cymru
* Tîm Amgylcheddol Cyngor Bwrdeistref Sirol Rhondda Cynon Taf
* Tîm Amgylcheddol Cyngor Bwrdeistref Sirol Merthyr Tudful
* ecolegwyr arbenigol sy'n goruchwylio’r gwaith o adleoli rhywogaethau.

Translation:


 
The 11 mile stretch of the A465 section 5 and 6 runs through a diverse landscape. It includes:


* the built\-up urban areas around Merthyr Tydfil
* towns and villages
* post\-industrial sites
* farm land
* forests
* reservoirs


There is also a wide variety of terrain that characterises the Heads of the Valleys. This determines the area’s biodiversity.


Supporting biodiversity along the route of section 5 and 6 is important. The road is designed to keep to the area’s natural landscape and cultural features.


We carried out environmental surveys before the building work started.


It’s a big project, and so far we’ve carried out:


* 100 inspections
* 313 environmental observations
* 4,000 hours of ecological supervision


This has helped us to work out what kind of wildlife lives in the area. We also looked at the soil and plants to see what kind of habitats can support the wildlife.


### **What we found**


The surveys showed that there were several species living along the route. These included:


* bats
* dormice
* great crested newts
* lapwings
* marsh fritillary butterflies

### **How we’ll protect the wildlife**


To make sure that these species have the space they need to thrive, we’re:


* creating new habitats away from the road, including heathland and woodland
* moving Devil’s\-bit scabious, a plant which supports marsh fritillary butterflies
* installing bat houses
* creating a great crested newt pond
* removing, storing, and re\-using topsoil
* buying land for new, managed, lapwing breeding sites
* moving marsh fritillary larval webs to safe areas, including farmland
* installing 421 pitfall traps within fenced\-off areas to move over 1,000 amphibians or reptiles safely from the works. These include:
	+ 57 great crested newt
	+ 123 palmate newt
	+ 61 common frog
	+ 496 common toad
	+ 65 common lizard
* moving dormice to a new habitat in 6\.33 hectares of land
* growing 8,000 plants which support marsh fritillary butterflies
* removing plants which destroy structures and make it harder for helpful plants to grow
* planting over 55,000 new trees and shrubs to replace the ones we removed to build the road


This regulated work is being monitored by:


* Welsh Government
* Natural Resources Wales
* Rhondda Cynon Taf County Borough Council Environmental Team
* Merthyr Tydfil County Borough Council Environmental Team
* specialist ecologists supervising the relocation of species
