Earliest Botanic Gardens

Padua Oldest surviving 1545
Paris 1597
Florence 1545
Edinburgh
Dublin
As time went on, more gardens have been established. Since 1950 more than half of them have been established.
What is a Botanic Garden? 1960s “Open to the public where the plants are labeled.”
Today’s definition: “an institution holding documented collections of living plants for the purposes of scientific research, conservation, display and education.
2,500 botanic gardens today. Database online. 155 countries
Many new gardens being established today. Thailand, China, Manizales, Columbia, Bordeaux, France, Eden Project, UK (domes)
Why new gardens? Taken on a new mantle as institutions for plant conservation: BGCI
Since 1990s: many news areas of science, seed banks, biodiversity, public education, environmental protection and promoting sustainability, linked more to local communities
A GIANT NOAH’S ARC FOR THE PLANET
c. 100,000 plants in collections
Number of visitors: 250,000,000 per year
Conservation is a key driver in BG
c. 400,000 plant species worldwide
100,000 species now threatened with extinction
2/3 will b e threatened by end of century.
International Agenda for BG, Global strategy for Plant Conservation. By 2020 loss of plants will be halted. He’s been working on this for the past 10 years. Adopted by 188 countries worldwide. (U.S. has not signed!) Global strategy for plant conservation was adopted as part of the biodiversity convention. United States, Vatican, and Andorra have not signed
Fear that private companies will not have the right to exploit plants from around the world, but they won’t anyway. Countries have control over the use of their own plants. Hopefully countries will sign within the next few years.

Mexico: Lots. 1990s many created, mostly associated with universities. Growing native plants is the focus
How does our garden compare to the gardens of the world? Santa Barbara Botanical Garden – focus on native plants. Scientific research, education, education for plants. Closely linked to local community Santa Barbara. Leadership, converting many gardens to grown natives for horticulture, not just for conservation. Education FOR plants, advocate for plants. New way of education Why is this plant important. How does it impact on our lives? BG as site for popularization of native plants. Water issues in California. Invasive plants are a problem. Climate change can affect how plants spread. We should concentrate on growing our own.
The importance of plants:
Plants as fundamental natural resources. We need to make people more interested in plants. Jackson told of guiding kids on a tour of a garden, and talking and talking about the plants. He then overheard two children:
First Kid: Plants are boring.
Second Kid: You’re wrong. Plants aren’t boring. Only botanists are boring.
In England, Botanical Gardens as site for elementary education. Jackson thinks BGs should be linked to both formal and informal education. Some programs include, Plants and diversity, climate change, linked to National school’s curriculum. But not recognized by the Dept. of Education, the school authorities. Local teachers appreciate them and work them into their programs.
Missouri BG in St Louis has international programs in plant taxonomy, China, South America, etc.
400-600 delegates will come to Dublin. 13-18th of June, 2010
Medicinal Plants: 300 BGs have medicinal plant gardens. China and India use more than 5000 plant species for the primary health care. His research interest 300 plants in Ireland used for ailments. More or less this is lost. Today, only 2-3 plants are remembered as medicinal in Ireland.
