SAWFISH NEWS: Havenworth Coastal Conservation Meet and Greet with Sawfish Experts
Contributed by Tonya Wiley, Havenworth Coastal Conservation

During the 20th century, the population of smalltooth sawfish in the United States experienced a significant decrease in numbers and range due to overfishing, habitat loss, and limited reproduction. In response, NOAA Fisheries listed the U.S. population of smalltooth sawfish as an endangered species under the Endangered Species Act on April 1, 2003.
At the time of the listing in 2003 scientists knew little about the biology, ecology, and population dynamics of smalltooth sawfish. Over the last 20 years, scientists from multiple agencies, universities, and organizations have collaborated to research the smalltooth sawfish population in the United States. We now know more about their size and age at maturity, the number of young they give birth to, the food they eat, their large- and small-scale movement patterns and habitat use, and their response to a variety of stressors. This research greatly improved our understanding of the species and helped us prioritize the actions needed to reach recovery as quickly as possible.
To celebrate the progress made over the last 20 years and to share the plight of this endangered species with the public, we invite all to a meet and greet with sawfish experts on March 31, 2023 6-8 pm at the Ivey House in Everglades City, Florida. We’ll air a short sawfish documentary created by John Anderson with Terramar Productions, answer questions about sawfish research and management, and give away some free sawfish swag.
While we have achieved a lot over the last 20 years, there is still work ahead in recovering the population of smalltooth sawfish in the United States. NOAA Fisheries has a Recovery Plan that lists actions necessary to rebuild the population and some actions specifically require help from the public, so come join us and see how you can become involved!
If you catch or see a sawfish, please share the information with scientists by visiting www.SawfishRecovery.org, calling 1-844-4SAWFISH, emailing sawfish@myfwc.com, or using the FWC Reporter App.

BACK ON THE BIG SCREEN! DC Environmental Film Festival
Contributed By DCEFF
DC’s Environmental Film Festival returns March 16-26 with an exciting line-up of events.

The Environmental Film Festival in the Nation’s Capital (DCEFF) gears up for its much anticipated return of in-person events after a three year pause on live screenings due to the pandemic. Entering its 31st year, the festival will resume its public screenings from March 16-26 across multiple venues in D.C., including the Naval Heritage Center, Landmark E Street Cinema, the National Geographic Society, various Smithsonian Museums, Embassies and other cultural organizations. Festival-goers are already inquiring about this year’s film lineup and special events.
The Festival opens with an exciting D.C. premiere of Deep Rising (Matthieu Rytz, narrated by Executive Producer Jason Momoa), fresh from its world premiere at Sundance which tells a riveting story about a destructive secretive organization empowered to extract massive amounts of metals from the deep seafloor. Other film highlights include Oscar nominated All That Breathes (Shaunak Sen) centered around protection of the black kite bird of prey, Geographies of Solitude (Jacquelyn Mills) acknowledged by NY Times for its contemplative presentation of the rich ecosystem of Sable Island, and many other multicultural selections that feature stories from around the globe which will be screened at local embassies throughout D.C.

DCEFF has long been known for its lively programming and dedicated partnerships which entertain and educate about a wide range of environmental topics. This year’s highlights include a return of The Forum, a thought-provoking talk-series that explores critical themes, issues and trends such as Storytelling During Times of War: A View from Ukraine. This particular panel will feature two guest filmmakers from Ukraine to discuss the power and importance of visual storytelling in times of crisis as well as the prospects of a “green” post-war reconstruction for Ukraine’s energy infrastructure.
DCEFF also introduces for the first time a live pitch contest which offers emerging BIPOC filmmakers the opportunity to win a $12,500 grant towards the production of a short or their first feature film. Finalists will have a unique opportunity to be mentored by Judith Helfand (co-founder Chicken & Egg Pictures, award-winning filmmaker).
As public interest in environmental stories continues to grow, DCEFF will continue virtual programming in a hybrid festival model to allow for enjoyment outside of the local area. Audiences who cannot attend in-person screenings can look forward to a diverse selection of themes with films that challenge environmental threats and support proactive and sustainable action.

Marine Heatwaves Decimate Sea Urchins, Molluscs & More at Rottnest

Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Lead author Adjunct Professor Fred Wells, from Curtin’s School of Molecular and Life Sciences, said the west end of Rottnest Island had suffered a “catastrophic decline” in biodiversity.
“Since 1982, we have monitored biodiversity of marine molluscs and echinoderms including sea snails, clams, starfish and sea urchins on rocky reefs at Rottnest Island, Cottesloe, Trigg Point and Waterman,” Professor Wells said.
“Despite being sanctuary zones with the highest level of protection from human activities, we found that Radar Reef and Cape Vlamingh at Rottnest Island had suffered a catastrophic decline in biodiversity between 2007 and 2021, likely due to exposure to the warm Leeuwin Current.

“By contrast, the metropolitan coastline, which is not under the influence of the Leeuwin Current, was found to have well-preserved biodiversity and species richness.
“Overall, at the west end of Rottnest Island, the rocky reefs are badly depleted with a decline of 90 percent or more in biodiversity and density of molluscs.”
Professor Wells said a number of marine heatwaves on the west coast of WA in recent years that caused abnormally high ocean temperatures had impacted the area’s marine plant and animal populations.
“Our surveys in 1982 and 2007 showed Radar Reef and Cape Vlamingh had a mixture of tropical, temperate and WA endemic species. With increased sea temperatures we expected to see the proportion of tropical species increase, but this did not happen at the West End of Rottnest where all three groups declined substantially,” Professor Wells said.

“These findings demonstrate that even with the high degree of protection from direct human activities, these areas are not immune to the effects of global climate change.
“As far as we know, molluscs and echinoderms on other rocky reefs at Rottnest and other areas off the metropolitan coast are in reasonable numbers and we hope that in the near future these can provide larvae for repopulating Radar Reef and Cape Vlamingh.”
Published in Frontiers in Marine Sciences, the research is titled ‘Responses of intertidal invertebrates to rising sea surface temperatures in the southeastern Indian Ocean and is available online here.
