Problem garden area

I just don't know what to do with the area to the right of my summer house. It is super weedy and so I have covered it with black weed suppressing material and have put my compost heap and log pile down there for the woodburner.
There are also a lot of raised ash tree roots and I need access to the back of the summerhouse as I keep the lawnmover there out of site under a cover.
It is also a pet graveyard, I have four of my own cats buried down there and an assortment of other pets that I found whilst digging the flower beds belonging to previous owners of my house, I gave them all a decent burial together.
I have no idea what to put on top of the black plastic to make it look nicer and that area of ground is very bumpy and uneven so slabs are out.
I'd like a memorial to the animals and maybe some planting up the fence under the tree, I could grow some climbers there. Chunky woodchip isn't an option. I've tried that and the birds kick it all over the garden!
I'm stumped.

Yes, it is a tricky spot Lou. Is it too bumpy for some strategically placed stepping stones?
They could give you a pathway for access and you could fill in with gravel/plants that don't mind getting trodden on.
Does the area in front of the compost bins need to be sweepable to keep it tidy?
It's too bumpy for stepping stones even small ones. It doesn't need to be sweepable really. I did consider decking at one point but I think the compost heal is a bit too heavy for decking unless I build the decking around it.
Difficult to tell from the photo but is it sloping up towards the tree and compost area?
I was thinking about your decking idea. Would it be possible to do it as a raised path beside the summerhouse? Like a bridge over the bumps, a mini pier or boardwalk if you like.
Am I crazy?
Not sure how you could do it, just trying to think outside the box.
I think it could be done! It could even be extended round the back and the other side, would also hide the ugly plastic base of the summerhouse. We had ecobase put down in case we ever wanted to get rid of the summerhouse and make it back into a planting area, it can just be removed.
Phew, wasn't sure if my post made any sense. I had an image of a wooden covered train track kind of thing in my head.
I suppose the biggest problem would be finding the levels for the base. You could put gravel/planting around the awkward edges but have a clear walkway to the mower.
