[ERA Webinar] Invasive Plants Part I : Troublesome guests? Or misunderstood members of Ecosystems?

What are invasive species? Why do some species become invasive in the context of changing bioclimatic conditions? What is the appropriate scale of space-time for defining invasion? Does our language around invasion need reconsideration? Importantly, what role do invasives play in restoration? Can they be beneficial under certain circumstances? How do we best deal with species invasion in a given ecosystem? 00:00:00 – Introduction to ERA 00:01:17 – Overview of the discussion 00:05:29 – Megha Ojha presents a trait based approach to understand invasive plant species 00:08:09 – What is “invasive” as defined by an invasion biologist? 00:09:38 – Why everything that is alien/non-native is not necessarily invasive. 00:11:44 – What makes a species invasive? 00:17:05 – Questions for Megha 00:20:22 – Introducing Dr. Geetha Ramaswami 00:22:44 – Invasive species in different habitats 00:24:54 – The impacts invasive species 00:28:20 – Alteration of ecosystem processes by invasive plants 00:29:08 – Case study of Lantana camara 00:34:55 – An ecological framework to optimize invasive alien plant management 00:39:01 – Introducing Dr. Rohan Shetti 00:44:05 – Differentiating 'Pioneering' from 'Invasion' 00:48:08 – Dr. Shetti shares a restoration story (Norway Spruce) 00:59:13 – Drawing parallels between Norway Spruce and Eucalyptus in India 01:01:08 – Case study: Castor 01:02:42 – Problems with chemical treatments: The case of Indigofera hirsuta (invasive in the US) 01:04:46 – The restoration dilemma: How do we decide the best strategy? 01:07:11 – It’s better to treat the cause, than the effect 01:08:29 – Introducing Suprabha Seshan 01:09:38 – Suprabha talks about the Gurukula Botanical Sanctuary 01:12:50 – Industrial civilization, monocultures and mining 01:16:17 – Are plants deemed “invasive” actually responding to the catastrophe of pollution and destruction of the natural world? 01:18:19 – Is Lantana destroying biodiversity compared to habitat toxification and fragmentation?
