I think this is due to the geometry of your document. There's a left
margin that pushes the tikz picture to the right.

You can use the preview package to trim the output so that it leaves,
for example, 1pt on all sides of the tikz pictures. Here is a compilable
example.

%% ================================
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{mindmap}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\setlength\PreviewBorder{1pt}

\begin{document}
\begin{tikzpicture}
  \path[mindmap,concept color=black,text=white]
    node[concept] {Ecological Impact Assessment}
    [clockwise from=0]
    child[concept color=green!50!black] {
      node[concept] {Ecology}
      [clockwise from=90]
      child { node[concept] {theory} }
      child { node[concept] {field skills} }
      child { node[concept] {methods} }
      child { node[concept] {software engineer\-ing} }
    }
    child[concept color=blue] {
      node[concept] {Legislation}
      [clockwise from=-30]
      child { node[concept] {EIA} }
      child { node[concept] {Policy and Planning} }
    }
    child[concept color=red] {
      node[concept] {Data Analysis}
      [clockwise from=-30]
      child{node[concept]{Statistics}}
      child{node[concept]{GIS}}
      child{node[concept]{Decision Science}}
    }
    child[concept color=orange] {
      node[concept] {Professional Practice}
      [clockwise from=-75]
      child{node[concept]{Business skills}}
      child{node[concept]{Presentation skills}}
      child{node[concept]{EcIA best practice}}
      };
\end{tikzpicture}
\end{document}

Are you developing a mindmap exporter for org? If so, I am very
interested ;)

Best,
