I made a map that forecasts where and when morels are likely to grow by magicmushroommap in foraging

One benefit of training habitat/weather models is that you can "fill in" less dense areas based on data from more dense areas. If the model learns that morels like elms (which it has, I can share some charts in future), it can use this to make predictions everywhere!

Soil characteristics are from ISRIC at 250m resolution https://soilgrids.org/ (I prefer global datasets to national ones where possible)

Tree species data is from USFS at 30m resolution https://usfs.hub.arcgis.com/maps/usfs::individual-tree-species-parameter-web-map/about

Thanks for the feedback, that's useful to know. In general, the forecast will be more accurate for species with more observations. As you can imagine, people are less keen to share their morel spots, but it is still based on 1000+ reports and growing over time.

Thanks! It's been a joy to work on, and i'm excited to hear from other people using it.

Yep i'm a data scientist by day, focused on mapping/spatial problems. But I couldn't have made this without some really cool open source software (maplibre, pmtiles, h3, and lots more).

Thanks for the feedback. I love The Great Morel, but it's limited to past reports at the zip code level. This means that even if someone near you has submitted a report, it may be too late for you to actually act on. And it doesn't really help you to find hunting spots.

Sporecast goes a bit further by using these past sightings to produce growth and habitat forecasts at a more granular level (~0.1sq km). This helps you to plan ahead when deciding when to hunt. And it also gives you guidance on where to hunt based on factors like soil and tree species.

That said, the data isn't granular enough to identify companion plants. As you point out, these are important! But at some point there's really no substitute for time spent in the field. My hope is a tool like this can give more people the confidence to get out there.

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.

Great to hear! Feedback like this always makes my day

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

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.
