“The invasive species Alliaria petiolata (garlic mustard) increases soil nutrient availability... plots invaded by A. Petiolata were consistently and

significantly higher in N, P, Ca and Mg availability, and soil pH...

...The results presented here... suggest that this invasive plant may change soil nutrient availability in such a way as to create a positive feedback

between site occupancy and continued proliferation....” (Rodgers et al, 2008)

ecological indicatorshuman nutrient deficiency

“...vitamin C (Ascorbic acid) is associated with history of an unrelenting search for the cause of the ancient hemorrhagic disease scurvy....” (Iqbal et al, 2004)

... Ascorbic acid deficiency has been shown to be a conditioning factor in the development of gingivitis. When humans are placed on ascorbic acid deficient diets there is increased edema, redness

and swelling of the gingiva...” (Nakamoto et al, 1986)

keys to successEcosystems People

Understand general processes and 

unique site‐specific circumstances

Document symptoms, timing. 

Assess a sample 3‐day diet diary.

Understand site /public 

/stakeholder context 

Consider family history. Social 

and/or professional support highly 

variable from patient to patient.

Select goals that are: specific, 

achievable, measurable, 

understandable, flexible

Serum values of nutrients are 

widely tested in research. Targets 

are generally easy to achieve, 

measure and understand.

Conduct long‐term monitoring 

and evaluation

Do regular blood work, document 

changes in function/symptoms, 

adapt regimen if/as needed. 

Conduct more in‐depth 

investigations when needed.

restoration

monitoring

“Ecosystem restoration ... is generally far costlier than

protecting the original ecosystem... it is rare that all

of the biodiversity and services of a system can be restored...” (MEA, 2005)

“A stitch in time may save nine...” (Fuller, 1732)

“An ounce of prevention is worth a pound of cure...”

(Franklin, 1735)

Restoration ecology and mainstream human health care in Canada are typically reactive approaches.

By employing proactive approaches to human and ecosystem health, better outcomes can potentially be achieved for all.
