Afire: Fire Ignition, Mitigation & Recovery 48:22

6M ago48:22

48:22

Fire shapes landscapes and lives, but how do humans shape fire? By measuring wildfire ignition, mitigation, and recovery, as well as the wildland-urban interface—where houses meet or intermingle with undeveloped wildland vegetation—scientists are uncovering the complex dynamics between wildfire and human behavior. Research social scientist, Miranda…

Afire: Understanding Fire Differently 48:21

7M ago48:21

48:21

Indigenous tribes gained their unique understanding of fire, and the role of fire on the landscape, long before European settlers came to what is now called North America. Since then, the relationship between federal fire management and indigenous perspectives has often been one of misunderstanding and mistrust. On Episode 2 of "Afire," join Forest…

Afire: Understanding Fire 1:06:09

1:06:09

Fire is a form all of its own, but a simple way to understand fire is as a swarm. A swarm of bees. Or starlings. Or mosquitos. A spreading fire is a swarm of ignitions, a series of small fires over and over. Season 4 of Forestcast is a series of fires, a series of voices. It’s a 360-degree introduction to fire from a scientific standpoint. The stor…

44:49

Once spanning nearly 6 million acres in Missouri's Ozarks, the shortleaf pine and oak woodland ecosystem has dwindled to 100,000 acres today. Along with the loss of this habitat, a bird—the brown-headed nuthatch—disappeared as well. However, after decades of woodland restoration, the brown-headed nuthatch has returned to Missouri—by plane. Over two…

Backcross: How A Bird Influences Beech Resistance Patterns (BONUS) 26:51

2y ago26:51

26:51

Beech bark disease has been killing American beech trees in eastern North America since the late 1890s. In northern New England, New York, and the Maritimes where the disease is most severe, groups of disease resistant trees occasionally occur. Genetic studies reveal that trees in groups are families, and distribution patterns suggest that they wer…

Backcross: Will Ash be the Blueprint for Tree Restoration? 24:13

2+ y ago24:13

24:13

The number one way you can stop an insect invasion or pathogen from spreading is by stopping it from ever starting. Who says geneticists and ecologists can’t act in the same way—taking action before a tree is ever in danger? With ash, proactive and collaborative breeding is already taking place, and it could be a roadmap for the future of combating…

Backcross: A Return to Elm Street 29:23

29:23

Dutch elm disease (DED) is one of the most commonly known and destructive tree diseases in the world. The disease was first observed in Ohio in 1930, and by 1976, only 34 million of the estimated 77 million elms present in U.S. urban locations remained. Research on American elm from the 1970s to the present has focused in large part on the identifi…

Backcross: The Past, Present and Future of American Chestnut 41:06

41:06

A hundred years ago, the American chestnut was the redwood of the East. It was big, and it was everywhere, especially in the southern Appalachians. But, today, it’s just a shrub and is, functionally, extinct. With chestnuts having gone through such a dramatic decline, restoration has been a priority, and it’s been a restoration effort unlike many o…

Backcross: How Do You Breed Better Trees? 19:40

19:40

Tree species restoration—especially with species that are threatened with extinction—isn't even on the table unless you have resistant planting stock. But, trees live on another timescale than humans—a much longer one. And, to be a geneticist, to breed, your job is to infiltrate that timeline, and to understand it. By understanding that timeline, y…

In season one of Forestcast, entomologists showed us the ways we slow insects from attacking and killing trees. This season, we’ll meet another set of scientists, scientists who have been attacking the issue of non-native invasive insects and pathogens from a different angle. Chemicals and biological control can buy trees time, but they cannot comp…

A Window of Resurgence for Red Spruce 37:22

37:22

In the 1970s, red spruce was the forest equivalent of a canary in the coal mine, signaling that acid rain was damaging forests and that some species – especially red spruce – were particularly sensitive to this human induced damage. In the course of studying the lingering effects of acid rain, scientists came up with a surprising result – decades l…

Balance & Barrier: The Hornless Asian Longhorned Beetle 18:42

4+ y ago18:42

18:42

The Asian longhorned beetle has the makings of a disaster pest poster — a wide possible geographic and climatic range, a number of host trees, and few control options. Lucky for us, it just doesn’t seem to spread far on its own. There are biocontrol and predator options, but nothing is ideal, or especially effective. At this time, there isn’t much …

Balance & Barrier: When A Single Clone Caused An Invasion 25:06

25:06

With no parasitic wasps — like we have for emerald ash borer — and no miracle fungal pathogen — as with gypsy moth — our control options for the nonnative insect threatening Eastern hemlock forests, the hemlock woolly adelgid, have been tricky. Hemlock forests, and the hemlocks in your yard, are paying the price. Related Research: “Hemlock Woolly A…

Balance & Barrier: Slowing the Spongy Moth's Spread 18:46

4+ y ago18:46

18:46

Insect biological control comes in all shapes and sizes — parasitoids, predators, or pathogens. So, what happens when neither a parasitoid nor a predator are feasible? Well, sometimes we have to turn away from using insects to attack insect pests, and turn to using an even smaller organism, something microscopic: a pathogen — in this case a fungus.…

Balance & Barrier: Wasps vs. Emerald Ash Borer Beetle 25:28

4+ y ago25:28

25:28

With global trade and travel, organisms are moved around easily and abruptly, causing biological invasions. What’s our best hope to combat these rapidly spreading pests? Sometimes, it’s to do the exact same thing, to start moving around organisms — on purpose — to attack unwanted pests. This is called ‘biological control.’ It is one of the most cos…

Balance & Barrier: A Slow Explosion of Damaging Forest Insects 23:15

23:15

A biological invasion is an enormous increase in population of some kind of living organism. It happens when an organism — like an insect — arrives somewhere beyond its previous range, when it breaks out past its natural barrier, unbalancing the biological order. More than 450 non-native insects have invaded our forests and urban trees since Europe…
