Demands and expectations on protected areas

 Objectives of protected areas
  have changed and diversified
  over time
 Competing demands have
  made management more
  complex
 Competing objectives makes
  clear identification of values
  critically important
 Planning and community
  engagement are needed to
  address competing demands

The likely successor to Aichi Target 11

Updated Zero Draft: The vision of the framework is a world of living in
harmony with nature where: “By 2050, biodiversity is valued, conserved,
restored and wisely used, maintaining ecosystem services, sustaining a healthy
planet and delivering benefits essential for all people.”
Framework has 20 action-oriented targets for 2030
“(a) Reducing threats to biodiversity
Target 2. By 2030, protect and conserve through well connected and effective
system of protected areas and other effective area-based conservation measures
at least 30 per cent of the planet with the focus on areas particularly important
for biodiversity.”
This focus on effective PAs and OECMs in the right places to
conserve biodiversity speaks to the question of “quality” that I
mentioned at the start of this talk
Current developments in assessing protected
                     area “Quality”

Green List and Thresholds
•   Indicator 3.7.1 - Each of the major site
    values is monitored and has defined
    performance measures which provide an
    objective basis for assessing if the value is
    being successfully protected
•   Indicator 3.7.2 - A threshold level has been
    specified for performance measures that, if
    achieved, demonstrates objectively that the
    associated major site value is being
    successfully protected
Green List Guidance
•   Thresholds can be established in many ways…: values taken
    from scientific literature, comparison with past measurements, ecological
    modelling, values set by legislation or regulation and/or expert consensus.
    In all cases, the reasons for the selection of the threshold should be
    documented...

•   Each of the site’s major values should be assessed against a
    performance threshold as the basis for determining conservation success in
    relation to the associated value.

•   Thresholds will rarely be absolute and may be refined as knowledge
    improves. Thresholds should not be arbitrarily changed to accommodate
    changes in management performance.
•   Guidance - Thresholds should establish the condition of the natural value as
    being good, fair or in poor condition
Good                                       Good with some concern             Fair                                              Poor

Green List in the News

"IUCN’s Green list is the most important international
certification of excellence concerning governance of
protected areas. It’s with great honour that we
acknowledge that three Italian national parks
(Arcipelago Toscano, Foreste Casentinesi and Gran
Paradiso) met this goal. This is an outcome in which
the Ministry has invested and it shows the value of
our precious natural capital, not only in terms of
biodiversity protection, but also around its overall
management,"
Roberto Cingolani, Minister of Ecological Transition
of Italy.
Recently, there has been a lot of interest from Asian
region about the IUCN Green List and KNPS is ready
to share our experiences and knowledge with global
communities. Managing protected areas effectively
will be important in the post-2020 Global Biodiversity
Framework. I believe that the IUCN Green List will
play a crucial role in post-2020 period.

UN CBD Decisions –Post-2020

CBD COP 13, Mexico
  • Decision XIII/2 “promote the IUCN Green List of
    Protected and Conserved Areas as a voluntary standard
    to encourage protected area management effectiveness”

CBD COP 15 - POST 2020 Framework: the IUCN Green List
Standard is proposed as measure for the quality elements of
protected areas for biodiversity and climate change (Target 2)
proposed by the CBD Secretariat in CBD/SBSTTA/24/3Add.1
Green List ambition?

Experts agree that a scientifically credible and necessary interim goal is to achieve a
minimum of 30% protection by 2030

Why not 30x30x30 with 30% of the total extent of the world’s protected and
conserved areas achieving the IUCN Green List Standard by 2030
What would this mean in Australia

• Australia has >13,000 protected areas
• 10 largest protected areas in Australia represent 33% of total estate
• Engaging one hundred of the ~300 PAs over 50,000 ha in size would represent 33% of
  the total Australian PA estate
• All terrestrial World Heritage sites would cover >4% of the total Australian PA estate
