In 2011, following a 2009 fire that was the most deadly to humans in Australia’s history, it was observed that previously unknown and rare plants had emerged in Victoria’s Kinglake National Park. When fire clears out the vegetation cover preventing light from reaching the forest floor, dormant seeds lying in wait in the soil have a chance to flourish, allowing the ecosystem to start off on a new foot.

The current disaster completely eclipses that fire or any yearly fire season since then in terms of the amount of land consumed, though, and just because Australia’s ecosystem has the ability to bounce back from fires, that doesn’t soften the blow of the human and animal suffering that have taken place as immediate consequences. Worse yet, scientists say that more intense summer temperatures and droughts in recent years are making large-scale fires more likely as well as increasing the duration of the fire season.

In addition to all the animals killed in the blaze, many more that live in the forest understory or have specific diets have had their habitat destroyed, so casualties may continue even among the survivors after the fire has cleared out of an area. This aspect of the ecosystem won’t rebuild as easily and some of the affected animals are already endangered or close to extinction. Scientists have estimated that 30% of the koala population may have already died.

Organizations working to rebuild communities have had to send a word of caution to people abroad who want to help, though. Some organizations have received so many boxes of blankets and mittens for recuperating animals that they no longer have a place to store them and also aren’t too pleased with the environmental impact of international shipping.

People like to donate material goods because they feel like they know exactly what they’re being used for, but Juanita Rilling of the US Center for International Disaster Information urges people to realize that it is tremendously more practical to identify and send financial donations to organizations providing assistance to the animals and people that have lost their homes.
