Gofynnodd yr ymgynghoriad am farn ynghylch cynyddu'r trothwy ar gyfer ardaloedd nad ydyn nhw'n sensitif i naill ai 20 neu 50 hectar. Roedd cynnig yr ymgynghoriad y byddai'r trothwy ar  gyfer ardaloedd sensitif yn para ar 2 hectar neu lai a sero yn yr ardaloedd mwyaf sensitif lle caiff pob prosiect coedwigo ei sgrinio. Daeth 95 o ymatebion i law ynglŷn â hyn.  Er bod cefnogaeth eang o blaid creu coetiroedd, nid oedd y mwyafrif (80%) o blaid cynyddu trothwy'r ardaloedd heb sensitifeddau ac roedd llawer o'r farn y dylid gostwng y trothwy er mwyn diogelu cynefinoedd a bywyd gwyllt. Mae’r farn ar lefel y trothwy (fel y dangosodd yr ymgynghoriad) yn pegynu safbwyntiau rhwng y rheini sy'n credu y byddai cynyddu'r lefel yn gwanhau mesurau i ddiogelu'r amgylchedd a'r rheini sy'n teimlo y byddai cynyddu'r trothwy yn annog plannu mwy o goetir.
The consultation sought views on increasing the threshold for non-sensitive areas to either 20 or 50 hectares.  The consultation proposal was to keep the threshold for sensitive areas at 2 hectares or less and zero in the most sensitive areas where all afforestation projects will be screened.  A total of 95 responses addressed this issue.  Whilst there was widespread support for woodland creation, the majority (80%) of respondents were not supportive of an increase in the threshold for non-sensitive areas and many considered the threshold should be reduced to better safeguard   habitats and wildlife.  Views on the level of threshold (as evidenced by the consultation) are highly polarised between those who considered environmental protection will be weakened if the threshold is increased and those who consider an increase will encourage more woodland planting.
