In the Southeast\, fire is especially important to healthy native landscapes\, to conserve listed and at-risk species\, manage for wildfire risk\, and minimize the need to conserve species through regulation. Here we present new efforts to improve the accuracy and completeness of burned area mapping over existing datasets by extending the Landsat Burned Area Algorithm to the Harmonized Landsat and Sentinel-2 dataset. The results of this effort will increase processing efficiencies and data accuracy. Most importantly\, the new burned area products will inform Southeast FireMap and ultimately promote better decision-making to prioritize funding for staff\, projects\, training\,\nequipment\, and allow fire partners to work smarter. \nMelanie Vanderhoof\, PhD\, is a Research Geographer for the U.S. Geological Survey\,\nGeosciences and Environmental Change Science Center in Denver\, CO. She uses remotely\nsensed data to explore how ecosystems respond to mechanisms of change\, such as climate\nextremes and wildfire. \nPresentation abstract: Remotely sensed burned area (BA) products are critical to support fire\nmodelling\, fire policy\, and land management. However\, BA products often require further\nprocessing before use\, even when delivered at an annual time-step. Fire management across the\nU.S. will benefit from comprehensive\, spatially explicit fire occurrence data\, delivered in a format\nto facilitate their direct use by diverse stakeholders. We produced a suite of contemporary fire\nhistory metrics from the Landsat BA products from 1984–2020 across the conterminous U.S. Fire\nhistory metrics\, alone\, or combined with historical or target fire regime data\, enables Landsat BA\ndata to help inform management of fire-dependent species and ecosystems\, fire behavior and\nemissions modeling\, fire risk analysis\, and prescribed fire planning\, all elements that are sensitive\nto fire history. \n  \nJosh Picotte has 15+ years of using field and remote-sensing based research for fire science\napplications. His infatuation with fire (and fire science) began while working at Tall Timbers\nResearch Station. He is currently working at USGS EROS on the MTBS\, LANDFIRE\, and SE\nFireMap projects.\nPresentation abstract: We developed regression models that describe the relationship between\nthe Composite Burn Index (CBI) field-derived and remotely sensed assessments (i.e.\, derivations\nof the Landsat derived Normalized Burn Ratio [NBR] index) of burn severity at different\necologically relevant scales for the conterminous United States (CONUS). Overall\, we found a\nreasonable goodness of fit (R2) of 0.55 for the differenced NBR (dNBR) and a poor fit (R2 = 0.33) for NBR at the CONUS scale\, and much better fits (R2 ≥ 0.75) for some smaller scale vegetation classifications. We will discuss how our simple decision tree framework allows a user to decide which scale and model may meet their needs to transform remotely sensed to on-the-ground burn severity metrics. \nHolly Nowell\, PhD\, joined Tall Timbers in August of 2022 after completing a post-doc\nat FSU where her studies included analyzing biases and uncertainties in the satellite\ndetection of fires in the Southeast United States\, as well as modeling their emissions.\nHer current work at Tall Timbers will focus on various aspects of SE FireMap including\nassessing regional patterns and impacts of burning on ecosystem services\, and\npredicting and communicating the uncertainties in the burned area product.\nPresentation abstract: This talk will show some preliminary research and discuss upcoming\nresearch on how to use SE FireMap to conduct landscape-level analysis of burning trends across\nthe Southeast US region. Current areas of focus in the preliminary work include temporal trends\nin burning on public vs. private lands in non-agricultural settings at a county level.

SUMMARY:Covey Film Fest Screenings at Tall Timbers
DESCRIPTION:Please join us at Tall Timbers on January 25\, 2023\, for an evening of conservation films. We will be screening “Introducing the Indigo\,” “Okefenokee Destiny\,” “Oshkigin Spirit of Fire\,”  and “Okefenokee Swampin – On the Fly.” \nThe evening will begin with an outdoor social at 6 p.m.\, including wine and cheese. Films will follow at 6:45 p.m. and conclude around 8:30. \nAdmission is a $10 donation at the door\, or on the Covey Film Fest website. \nThe great local team of Laura Albritton and Zickie Allgrove will introduce and discuss their new short film “Introducing Indigo.”  \nRena Ann Peck\, Executive Director for the Georgia River Network will Join us to introduce two short films about the Okefenokee Swamp and efforts to protect the swamp and other natural areas from a proposed sand mine.  \nFilms being screened at the event: \n\n“Introducing the Indigo” is a short film aimed at young audiences that highlights the rare\, threatened Eastern indigo snake. The documentary discusses the longest snake native to North America and its declining numbers. The film was produced by Magic Kumquat Productions\, out of Thomasville\, Georgia.\nA segment of the PBS aired EcoSense for Living program\, “Okefenokee Destiny” focuses on swamp ecology and explores the future of Okefenokee at a time when a proposed mining operation on its border threatens the largest intact Blackwater wetland in North America.\nThe short film  “Okefenokee Swampin – On the Fly” will open for “Okefenokee Destiny” and give insight into the sportsmen’s perspective on conservation of the swamp. The film was created by the local team of Christopher Watt and Drew Balfour. \nFor thousands of years in the Great Lakes Region\, Native Americans used fire intentionally to manage the ecosystems they lived in. Now\, there is a short film\, “Oshkigin Spirit of Fire\,” highlighting this deep\, reciprocal relationship with the land and the traditional use of fire in the Ojibwe culture. The filming took place\, with permission\, on the reservations of the Fond du Lac Band of Lake Superior Chippewa in Minnesota and the Red Cliff Band of Lake Superior Chippewa in Wisconsin.\n\n \n
