Lovatts Colossus No. 119 Giant Cryptic

Need some help to complete my puzzle!

61d Anti-war campaigners seen outside Pacific rain forests (9) = ?A????S?S
crosswords are 65s = ALA, 74a = ??E?D?R?PS, 77a SWAMI, 80a =
SLEIGHS.

66a = SKATE is this the right answer?

71a = OG?E?G?L (been thinking this word may be OGRESSES?) crosswords are 48d = ELEVATORS, 67d = EGYPTIAN,
58d = PEPPERING, 72d = ???????, 59d = TREE??????? 64d = ?C???????
82a ???????

Hope this isn't too confusing for once I haven't had time to concentrate for long enough.

Thanks
