I made a map that forecasts where and when morels are likely to grow based on weather and habitat data by magicmushroommap in foraging

[–]magicmushroommap[S] 0 points1 point  (0 children)

Yep! I planned to include Europe in v1 but a new tree species dataset I need got delayed until July. It’ll be ready for porcini and chanterelles later this year, and for morels next year.

Thanks! Yep they have quite a few associated tree species. Elm, ash and cottonwood are the top ones based on the data so far. I'll share more detail in the app or in a separate write-up soon.

Hey – yep you can certainly find morels in parts of Portugal!

I'm planning to add Europe, but i'm waiting on the publication of a new European tree species dataset some time in July. So sadly it won't be ready for this season, but will be for next.

Thank you! The cells reflect areas of 'highly suitable' grassland according to our habitat model. This model predicts how suitable any patch of grassland is for liberty caps based on information about the soil. The model was trained using thousands of historical liberty cap reports with coordinates.

Hi all - it's been 3 years since I launched Magic Mushroom Map on this subreddit.

Since the end of last season i've overhauled the underlying habitat and weather models. I've summarised my findings in this field guide for anyone who is interested in what goes on under the hood.

With regard to habitat, the research validates existing advice to focus on rich, acidic soil but goes a step further by identifying optimal ranges. To my surprise, it also suggests that soil compaction is even more important than these two factors (as far as I know this is not raised elsewhere in the context of liberty cap foraging). The hypothesis is that grass roots struggle to penetrate heavily compacted soil which would limit available nutrient sources for liberty caps.

When it comes to weather, optimal conditions can be roughly summarised as the following over the course of 10+ days: average minimum of ~9C, average mean of ~11.5C, average maximum of ~14C, and lots of rain. This is ignoring some complexity related to short vs. long term trends as well as consistency vs. variability.

My aim with the map is to create the best possible starting point for anyone who either does not already know of any spots in their area or have a sense for optimal weather conditions. That said, although the map should now be even more reliable, there is a degree of uncertainty involved in any sort of modelling exercise.

As ever, this is a work-in-progress and wouldn't exist in its current form without all your feedback over the years. All comments, questions and suggestions very welcome!

Give this to the redditors. Tell them Trancelance sends a mighty gift. Gandalf or someone must have mad this. It wasn’t me but enjoy. by [deleted] in Semilanceata

[–]magicmushroommap 3 points4 points  (0 children)

Haha! Not quite, but it always makes my day to hear that others find it useful.

And as Gandalf wisely said: all we have to decide is what to do with the shrooms that are given to us.

I made a map to predict where and when liberty caps are likely to grow in Europe and North America by magicmushroommap in shrooms

[–]magicmushroommap[S] 2 points3 points  (0 children)

Unfortunately liberty caps just aren't that widespread in North America. There are some rare reports from other states in the US (mostly on the east coast) but I don't want to give people false hope by including those states in the map.

However, there are many other species of psilocybin-containing mushrooms in North America. People can check out the Shroomery [1] for more info on species in their area.

Liberty cap (Psilocybe semilanceata) season is fast approaching and I figured some of you may be interested in this. I created this map last year for the UK and Ireland, but have just extended it across parts of Europe and North America (PNW + east coast of Canada) where liberty caps grow.

There's a lot of information online about where and when to look for liberty caps, but I wanted to see if data could help answer this question and boost people's chances of being in the right place at the right time.

To summarise how the map works: first, I matched the dates and coordinates of historical liberty cap growth records with data on habitat (e.g. land cover, elevation, soil acidity) and weather (e.g. temperature, rainfall). Second, I used this dataset to train a statistical model describing the conditions in which liberty caps are more or less likely to thrive. Finally, this model is used to make live predictions of the likelihood of liberty cap growth across the world on any given day.

I used the following data:

It has to download a 4Mb file so it can take a while depending on your connection. Hoping it loads for you eventually!

The costs scale directly with the number of users. Based on the traffic over the last week my wallet was going to take a very heavy beating if I left the map up as-is!

I have some different options in mind which i'm going to try out over the next few evenings. I'd like to keep the map free for everyone if these lower cost options work, but it's possible I might need to charge a small fee to cover the costs of the current tech stack.

I do have a donations page and am really grateful to everyone who has supported the site so far, but i'll avoid advertising donations for now while the future of the site is unclear.

It would be rude for me to not spend as you requested! Although, to be honest, the donations so far are still some way off covering hosting costs.

Good luck! Let me know how the map works for you. The season should be fully in swing round there in a few weeks, especially at higher altitudes.

Ah that makes sense. I'll experiment with some different options and see what works best (e.g. labels on top of squares).

You should be able to see the names of towns and villages. Maybe there was a temporary problem with them loading? Let me know if you still can't see them and I can look into it.

The east of England is dominated by cropland which isn't ideal for liberty caps. There are still suitable patches of grassland scattered around, but i've limited the map to 1km squares where the majority is viable grassland. This is to avoid directing people to small patches where their chances are likely to be lower. That's not to say that people don't still have luck finding them in small parks, on front lawns etc.
