Invasive species of plants are among the main threats to the future of Celtic rainforest, MSPs were told in January.

The woodland covers large areas of Scotland's Atlantic coast, including Knapdale, an area of Argyll that is home to the Scottish Beaver Trial.

Argyll and Bute SNP MSP, Michael Russell, has told Holyrood that non-native plants such as rhododendron smother rare native species.

He said public bodies and charities were trying to tackle the problem.

Scottish Conservative MSP Rachael Hamilton asks what action the government is taking to tackle the threat to woodland from invasive rhododendron. 

Green MSP Mark Ruskell asks if the cabinet secretary will include full liability for the environmental clean up of cleaning up after unconventional gas.

Ms Cunningham says the government is looking into this and addressing concerns.

Environment and Climate Change Secretary Roseanna Cunningham says this data is not available.

Ms Cunningham says the Scottish government does not hold this information and it is held in the country of origin.

Ineos says access to cheap US shale gas will transform the economics of Grangemouth.

And it believes that the creation of a chemical and manufacturing hub around the plant could pass that competitive advantage on to others.

But cheap US ethane won't just help Grangemouth.

Ineos has also signed a long term supply agreement with the Exxon Mobil/Shell Ethylene plant in Fife.

Scottish Conservative MSP Alexander Burnett asks how much carbon dioxide was released as a result of Ineos importing shale gas from the United States.

Mr Champan says the change has caused a great deal of concern in the farming community.

Rural Economy Secretary Fergus Ewing says the working group included the NFUS and they developed the new rules on linked holdings.

Mr Ewing says it is essential that disease control is in place to prevent against diseases like foot and mouth disease.

Scottish Conservative MSP Peter Chapman asks what action the government has taken to address the reported concerns of farmers and industry representatives regarding new rules on linked holdings.

More than 85% of households in Scotland now have access to fibre broadband, but reaching the remaining rural areas will be a challenge, according to a report.

Audit Scotland said it expected this figure to rise to 95% by December 2017 if BT continued to meet its targets.

However, extending coverage to rural areas will require "more complicated and costly engineering solutions".

The Scottish government also has "much to do" to achieve a world class digital infrastructure by 2020, auditors said.

That included defining clearly what "world class" meant and setting out plans for how it will be achieved, the report added.

The Scottish government wants everyone in Scotland to be able to access the internet at any time and on any device by 2020.

Scottish Labour MSP Daniel Johnson asks what action the government is taking to extend access to high-speed fibre broadband across the country.  

Connectivity Secretary Fergus Ewing says timescales for the fibre broadband roll out are available on the digital Scotland postcode checker. 

Mr Ewing says BT must deliver every quarter to get paid under the contract terms. 

SNP MSP Willie Coffey asks whether the government will publish a timetable for the installation of superfast broadband indicating when the service will be available in each area.

Scottish Lib Dem MSP Mark Ruskell asks what support the government provides to third sector organisations that seek to build a case for the reopening of rail lines and stations.

Transport Minister Humza Yousaf says he will engage with unions tomorrow.

Mr Yousaf says numbers of staff will be protected as will terms and conditions for British Transport Police (BTP) officers.

Police chiefs have warned that integrating railway policing into Police Scotland would be "massively complicated".

This would include the functions of the British Transport Police being taken over by Police Scotland.

Police bosses told Holyrood's justice committee that a merger would be "complicated but not insurmountable".

Representatives from BTP, Police Scotland, the Scottish Police Authority, and the Scottish Institute for Policing Research took part in a round-table session with MSPs at the Scottish Parliament.

Absorbing transport policing into Scotland's single force has been a long-running goal for Justice Secretary Michael Matheson.
