Harvest calendar for Yorkshire UK

This is only a guide for yorkshire, based on what I have seen in my local area. Therefore, I may not have everything that is available, but rather likely only things I have picked, or noted myself. I will try and remember to update this list as time goes by.

First though, some important rules for foraging:

1. Never take more than you need, and always leave plenty for wildlife, and other foragers, and for what you have taken to grow back for the following year. Over-harvesting of wild plants, leads to a lack of propagation, and reduction of plants available for the future. Many once-common plants are now rare due to over-harvesting in the past. Also, over-harvesting of flowers such as roses, or elderflowers creates a reduction in fruits later in the year
2. Do not pick endangered species, or those rare in your particular area
3. Never consume anything if you don't know 100% that it is what you think it is.
4. Leave no trace behind - respect the areas you are in, don't leave rubbish, and don't trample on other plants, or otherwise destroy or damage the local area. Not only is it bad for the ecosystem, and therefore the plants you are gathering, but it can also lead to owners stopping people from foraging in the future.
5. Seek owners permission before foraging on non-common land. We have a local area that is common land. Next to it is a field owned by a local farmer which is not common land. Though you likely wouldn't need permission to collect brambles from the common land, it would be best to ask the farmer to collect the crab-apples from the trees on the edges of his field. Many don't mind, if you are kind and offer something, such as jam or some pie in return, but if you don't it can be classed as trespassing.
6. Do not forage in polluted areas, such as those near busy roads.

Now for the guide.
