Can you discover which animal it is? Are there any footprints or spraints? I can only think of rabbits squirrels and deer that might do that. Does it choose particular plants and if so which?

I am not sure which animals and it seems to eat most plants with berries or flowers

On the internet you can find lists of rabbit proof and deer proof plants. There is a spray called Deer Off that is supposed to help deter both deer and squirrels - might help. If you could find any droppings it could help to identify the culprit. However some birds will also eat plants - have you got pigeons around?

Holly.

Before you start replanting have a look at 'Grazers' animal deterrent website. This product can also be purchased from all good garden centres.

Awooded area backs my garden too. Rabbits, groundhogs, skunks, raccoons, badgers and rarely, deer have been visitors. They know nothing of the effort that was placed into creating the garden and nor do they care. All they know is that they see is food and THEY WANT IN! and they will try to get in 24/7. If they do, my attitude is that they are welcome. I learned early on that keeping them out (I've tried just about everything)is a loosing battle with a wooded area next to or near the garden. I've had bad storms destroy more more of my plantings than they ever could. Of course this is my point of view.

I had cows on the front lawn once - now that's a mess to conjour with! They didn't eat any plants though...(Doesn't help with the present problem though...) Is there a spray to keep cows off the lawn??Lol.

Reminds me Steragram, of the situation here where city dwellers take their weekend drives into the country and are all taken in by the bucolic setting. Then they decide to move into the country to be a part of this idyllic scene next to a dairy farm or a crop farm. Once moved into their new country home, they one day, open their windows to take in that fresh country air, breathe deep, and are made dizzy from the smell of fresh manure from the cows, horses, sheep and cattle or almost pass out from the wonderfull aroma of the liquid fertilizer used by the crop growers. They then get terribly annoyed with the countryside critters that come to greet them in their new home both outside and inside (the sight of a hogna wolf spider in their living room makes the city "water bug aka cockroach" look like a pussy cat). Realizing that those beautiful rural scenes they saw on their yearly calendar pictures now has legs, so to speak, they actually begin to file complaints and attempt to change the zoning to rid themselves of what brought them to the peaceful farmland in the first place. This is now going on since many farmers have sold out to have their acreage turned into residential developments and the remaining farmers who are sticking it out now have to contend with this nonsense.

id be inclined to give them more of what they do like and invite them in . what a fantastic opertunity to be in touch with nature . id look at what the forestry do for planting for plants you do want .

Loostrife in a village not far from here some newcomers tried to get the village clock chimes turned off at night because they annoyed them - and in another village newcomers objected to the weekly bell ringing practice. Also heard of complaints abut cockerels crowing...

I still think a Holly hedge is the best deterent.

Acorns grew into huge Oak Trees all through history
because they fell into Brambles, they germinated.
Nothing ate the young trees because they knew about
prickles.
Thousands of Oak trees grew in England prior to 1066.
They survived because of the Brambles.
Years later the trees were cut down to provide the best wood for ships.

Just brought to mind that Spain was practically laid bare of trees in the construction of ships for several armadas hurled at England at that time. Today reforestation efforts are still ongoing to repair the damage done at that time.
