The mountain ash you can probably replace from a local nursery.
If you are patient you should try grafting for the Cherry and Apples. Take several cuttings of the year old sticks now, and keep them in a ziplock bag in the fridge.
Order some rootstock, most is picked over by now unfortunately so good luck, from Raintree, Cummins Nursery, Treeco, etc. Then graft onto the new rootstocks per the videos above.  (I  did a couple videos on YouTube, and Stephen Hayes is good too) Abundant Design on YouTube
If you are impatient, you can buy bigger trees from your local nursery in varieties of your choice.
If you want to try to save the trees you can try bridge grafting Bridge Grafting on YouTube

Check out a blurb on Guerrilla Gardening and a how-to video for Guerrilla Growing Paw Paws on public land by Quad Cities Edible Landscapes' Chris Rice.

Guerrilla Gardening is planting where you don't actually have permission, whether road ditches, along bike trails, abandoned lots or public parks & open spaces.  Guerrilla gardeners often see these spaces as neglected and ply their trade as a way to improve the space.  Sometimes vegetables and fruit trees are planted for food, while other times sunflowers and other flowers are used to beautify a space.  Fruit bearing branches can be attached to ornamental pear and crabapple trees by Guerrilla Grafters.  Even moss can be used as a form of "Green Graffiti."  Guerrilla Gardening can be used as a political act to encourage local food production, bring attention to urban blight or promote changes in land use policies.

Its like a May Basket that lasts longer

    What are you guerrilla growing?

A few elderberry on the inside of the bank might be a good addition.  Pollinator benefit, stabilize soil, and an edible/medicinal berry (and flowers too) that makes a great pancake syrup.  They do grow ~6-10' tall so take that into consideration.  Easily propagated from cuttings if you can find a patch nearby.

Thank you for your contributions to Permaculture and this site!
Glad you can be home and with family.
Peace to you and your family,
Jeff

Definitely try rooting cuttings and grafting, so fun to learn!
Late fall and winter are great for trying hardwood cuttings-


Late winter is great time since they are dormant but soon to wake up.  Get some rootstocks from ^Raintree and try it out with some cuttings/scion of your old tree.  
Here's 2 videos but there are so many available-



Good luck!

You could definitely try some hardwood cuttings this winter. I haven't had the best of luck (low %) with softwood cuttings under IM mist but am trying a bunch of hardwood cuttings this winter too.

Here's a link, several other methods to try too... http://fruitandnuteducation.ucdavis.edu/fruitnutproduction/Stone_Fruit_Propagation/sfcuttings/

Healing gardens are becoming more and more popular as ways to help patients reduce stress, feel at ease and actually improve recovery rates and shorten hospital stays.  

"Roger Ulrich was one of the first to promote a patients "View through a window..." can effect patient outcome - patients had fewer negative evaluative comments, took less medicine and averaged a day quicker post-operative recovery stays.  His influential work in the early 80's has been cited thousands of times and continues to influence healthcare facility design.  

Some of the documented benefits of Healing Gardens include:
  •Shorter post-operative stays
  •Less use of potent drugs
  •Better attitudes
  •Contribute to feelings of:
       -wholeness & health
       -calm, relaxed
       -the ability to think & cope
       -being refreshed
       -improved strength

More and more hospitals are adding healing gardens, especially for their Oncology and Alzheimer care units."

I am thrilled to be working on one in Des Moines and am incorporating many permaculture principles.

^ and lambsquarter is a delicious green itself!

Many "weeds" are also great for pollinators as well as the parasitic wasps and other beneficial insects.

From earlier this year: via Abundant Design

I've mentioned a study before showing increased yields in Blueberries, and research out of Texas has demonstrated cotton yield increases of 18% with improved pollinator habitat.

But Corn & Soybeans?
Iowa's largest commercial crops corn and soybeans don't rely on pollinators like many other crops.  However, new research by Iowa State's Matt O'Neal suggests growing more bee-friendly habitats could prove to be a worthwhile goal for soybean growers looking to improve yield.

"Three examples of earlier research include:
• A short-term Canadian study found bees’ presence was associated with much higher yields in food-grade soybeans.
• Australian researchers demonstrated yield increases of 10-40% in honey bee-pollinated soybeans, compared to self-pollinated beans.
• In 2005, a Brazilian research project compared soybean seed production with and without honey bee colonies by raising plants in cages, and reported 50% higher yields when bees were present."

Of course Permaculture Voices, and I don't think I've seen it listed yet so

My channel is Abundant Design, I blog weekly, but only occasionally with video content on YouTube, and not always strictly Permaculture.

Things in mine are pretty good for as much neglect I've done.  Hot and dry spells have affected the sweet & pop corn, I always put my tomatoes in too early so they stunt a bit.  Always a good producer I save in the compost bin
First year getting peaches on our 5yo trees from seed,and they are DELICIOUS!  Japanese beetles think so too, but I saved most tonight.  My Jonathon apple has no fruit, but the Macoun is ok, lots of blossom maggots though.  Strawberries did well, but a maple is rooting into my patch.  Got a few blueberries (most come from the inlaws), almost lost a sumac shrub, (too dry?) but it is recovering.  Lettuce good, squashes very good no borers or bugs yet.
Mixed bag, but mostly good.
Sorry for your troubles.
