Mae misoedd yr hydref a\u2019r gaeaf, pan mae coed collddail wedi colli eu dail a dim llawer o adar yn nythu, yn amser delfrydol i wneud gwaith rheoli coetir gweithgar. Mae hyn yn aml yn cynnwys technegau traddodiadol fel prysgoedio a theneuo.<\/p>\n

\"coed<\/p>\n

Ers canrifoedd mae llawer o goetiroedd wedi eu rheoli drwy brysgoedio. Mae\u2019r arfer hwn yn cynnwys torri rhai coed neu lwyni yn \u00f4l yn rheolaidd i lefel y ddaear, gan adael iddynt flaguro brigau newydd o\u2019r bonion a dorrwyd. Mae hyn yn cael ei wneud yn y gaeaf pan mae\u2019r goeden yn cysgu. Mae prysgoedio yn arwain at fwy o oleuni\u2019r haul uniongyrchol ac uniongyrchol yn cyrraedd llawr y coetir ac mae\u2019n gallu ysgogi twf planhigion coetir fel briallu a chlychau\u2019r gog. Mae deiliach a blodau\u2019r planhigion hyn yn ffynonellau bwyd ar gyfer anifeiliaid di-asgwrn-cefn sydd yn eu tro yn darparu bwyd i anifeiliaid eraill fel adar ac ystlumod. Mae\u2019r arfer hefyd yn sicrhau cymysgedd o ystod oedran ac amrywiaeth o goed, felly o fudd i amrywiaeth cyffredinol y coetir. Mae prysgoedio yn grefft coetir traddodiadol a ddefnyddir i dyfu boncyffion o goed syth a ddefnyddir ar gyfer creu dolenni ysgub, polion ff\u00e2, basgedi, clwydi ac ati. Mae sawl rhywogaeth coed yn ymateb yn dda iawn i brysgoedio, gan eu galluogi i bara am lawer o flynyddoedd, sy\u2019n golygu y gallant ddarparu bonion pellach o goed neu bren wedi\u2019i gynaeafu bob 5-20 mlynedd yn dibynnu ar y tocio sydd ei angen.<\/p>\n

Mae\u2019n bosibl y byddwn yn teneuo coetiroedd hefyd. Mae hyn yn cynnwys tynnu coed mewn cyflwr gwael, afiach neu orlawn i wneud gweddill y coed yn gryfach ac yn iachach. Defnyddir teneuo i reoli coetir sydd wedi\u2019i esgeuluso ble mae graddliwio trwchus wedi lleihau presenoldeb blodau gwyllt coetir. Mae teneuo yn digwydd yn aml mewn coetiroedd sydd newydd eu plannu i ganiat\u00e1u i goed cryfach dyfu\u2019n dda drwy roi mwy o le iddynt ffynnu.<\/p>\n

Oeddech chi\u2019n gwybod<\/strong>
\nMae coed mewn coetiroedd yn cyfathrebu gyda\u2019i gilydd drwy rwydwaith ffwngaidd neu \u2018we coed eang’! Mae ffyngau yn cynnwys edau cywrain a elwir yn fyseliwm sy\u2019n lledaenu o dan y ddaear ac yn cysylltu \u00e2 choed a phlanhigion eraill. Mae coed yn gallu defnyddio\u2019r rhwydweithiau hyn i gyfathrebu gyda\u2019i gilydd.<\/p><\/blockquote>\n

Mae llawer o fywyd gwyllt o fewn coetiroedd yn dibynnu ar reolaeth weithredol i ddarparu strwythur cynefin amrywiol, o bentyrrau o goed marw sy\u2019n gallu bod yn hanfodol ar gyfer rhai chwilod a ffyngau, i lennyrch agored sy\u2019n gartref i rai glo\u00ffnnod byw a pheillwyr pryfed.<\/p>\n

Mae\u2019r coetiroedd mwyaf amrywiol yn nodweddiadol yn cynnwys ystod o rywogaethau ac oedrannau coed gwahanol. Heb ryw fath o reoli gweithredol gall coetiroedd fod yn dywyll yn fewnol gan arwain at amrywiaeth prin o ran strwythur, oed neu rywogaethau. Yn y pen draw, mae hyn yn lleihau faint o fywyd gwyllt sy\u2019n gallu byw ynddynt. Drwy reoli coetiroedd yn gynaliadwy, rydym yn meithrin cynefin sy\u2019n fuddiol i goed, bywyd gwyllt a phobl.<\/p>\n

\"Coed<\/p>\n

Mae Iechyd a Diogelwch hefyd yn flaenoriaeth uchel ac mae coetiroedd yn cael eu monitro drwy gyfres o archwiliadau coed. Mae canfyddiadau o\u2019r archwiliadau hyn yn ein galluogi i weithredu\u2019n briodol i ddiogelu coed rhag pl\u00e2u a chlefydau tra\u2019n cynnal amgylchedd croesawgar ar gyfer ymwelwyr dynol.<\/p>\n

Pan mae coeden yn cael ei thorri rydym yn ystyried yr effaith ar y coetir a byddwn yn plannu coed yn eu lle ble bo\u2019r angen. Fodd bynnag, mae aildyfiant naturiol rhywogaethau coed lleol y dewis a ffefrir gan fod natur yn llenwi\u2019r bylchau sy\u2019n weddill yn raddol.<\/p>\n","protected":false},"excerpt":{"rendered":"
